                            <comment id="929183" author="JIRAUSER463015" created="Mon, 22 Feb 2021 20:05:06 +0100"  >&lt;p&gt;Hey Joe, this is a closed source program. I doubt they are willing to discuss the issues and mistakes with their code. &lt;br/&gt;
This was eye-opening for me. It took them over two months to fix these issues while the admins toiled away in despair. People in this forum had done far more troubleshooting than they had to, and pointed to the exact problems, yet it took a long time for them to fix the code (or even respond to my support tickets with absolutely incompetent replies). If we could see the source code we could have had it fixed probably on the same day. We could probably address many long-standing performance issues with the product as well.  &lt;br/&gt;
Additionally, to me, this means that I will be extremely careful and skeptical of products that are distributed via &quot;Stores&quot;. Especially when the updates cannot be rolled back and are not optional. luckily this is just a stupid game and doesn&apos;t make a difference in life of most people. I have other products that I manage that I&apos;m extremely worried about now. &lt;/p&gt;</comment>
                            <comment id="929161" author="JIRAUSER601837" created="Mon, 22 Feb 2021 19:25:30 +0100"  >&lt;p&gt;I pulled down a new server into my Docker environment, copied over the world files and can confirm that all looks good.  No more crash that once was very consistent.  &lt;/p&gt;

&lt;p&gt;Not that everyone cares but I&apos;m an IT geek - any way know what the issue was and what the fix was?  Always love seeing some insight into the code and the fix for a bug!&lt;/p&gt;</comment>

Thanks for addressing this! We had a rather large no-go zone in our world that we are glad to return to. &lt;img class=&quot;emoticon&quot; src=&quot;https://bugs.mojang.com/images/icons/emoticons/smile.png&quot; height=&quot;16&quot; width=&quot;16&quot; align=&quot;absmiddle&quot; alt=&quot;&quot; border=&quot;0&quot;/&gt;&lt;/p&gt;</comment>

&lt;p&gt;Same world does not crash on Windows.&lt;/p&gt;</comment>
                            <comment id="916779" author="tongfa" created="Tue, 9 Feb 2021 05:30:14 +0100"  >&lt;p&gt;Also seeing this issue.&#160; First noticed it on Realms.&#160; Then stood up my own linux server and could see the error log, and it&apos;s the same issue as this.&#160; If any Mojang developer needs help reproducing please let me know.&#160; I have a world that reliably reproduces this issue.&lt;/p&gt;

&lt;p&gt;thanks.&lt;/p&gt;</comment>

&lt;p&gt;Let me know if further testing and/or access is needed, we&apos;re not shy.&lt;/p&gt;</comment>

                            <comment id="905901" author="JIRAUSER463015" created="Wed, 27 Jan 2021 15:07:59 +0100"  >&lt;p&gt;I checked the server last night the world was corrupted and server was not working. The server has been offline (no access from users) but has been running. It seems like a couple of weeks ago the server somehow corrupted the world. I have nightly backups and restored the world from couple of weeks ago (after going back through several days of broken worlds) and everything is back to the way it was. This makes me wonder if a server crash, or the server just running idle by itself can actually corrupt the world. I guess I will find out in a couple of days that the server has been running to see if the world goes bad again. If that is the case this is yet another problem with this version. &lt;/p&gt;</comment>

After one of the crashes, some of the villagers despawned. The world is too big to attach here, but here&apos;s my &lt;tt&gt;server.properties&lt;/tt&gt; and the two Dockerfiles that I tried:&lt;/p&gt;

Running Bedrock 1.16.201.2 on Docker (on Windows)&lt;br/&gt;
Crash happens for any user but only when entering a certain area / within range of specific coordinates.&#160; Lowered the render distance from 10 to 6 chunks and was able to proceed further in a line before the crash and then respawned.&#160; Can fly around in a large circle without issue but then try to enter the circle and crash happens.&#160; &lt;/p&gt;

&lt;p&gt;Need to get confirmation status changed to confirmed. Is there a verified way to reproduce this issue?&lt;/p&gt;
&lt;/blockquote&gt;

&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;&lt;a href=&quot;https://bugs.mojang.com/browse/BDS-10926&quot; title=&quot;Bedrock Server (Ubuntu) crash on Village::getBedPOICount&quot; class=&quot;issue-link&quot; data-issue-key=&quot;BDS-10926&quot;&gt;&lt;del&gt;BDS-10926&lt;/del&gt;&lt;/a&gt; (which was closed as a duplicate of this bug) has&#160; a world file attached and repro steps to reliably reproduce the issue 100% of the time. It is very easy to confirm.&lt;/p&gt;</comment>

&lt;p&gt;If these people can&apos;t maintain their own software, they may either discontinue the product or just make the server opensource so people can fix this themselves. It has been over 5 weeks since they release the update. They have had enough time to start looking at the bug report. Maybe I&apos;m misunderstanding something here... This site is where the bugs for the Minecraft Bedrock Edition Dedicated servers are reported to the developers, correct? or at least I was under the impression that this was the place... am I at the wrong place?&lt;/p&gt;</comment>
                            <comment id="900820" author="JIRAUSER597806" created="Thu, 21 Jan 2021 10:16:54 +0100"  >&lt;p&gt;@Jam approximately 5 hours of play since villagers had somewhere to sleep again and no server crashes to report. Hope it is something that can be fixed as easily as moving the null-pointer check and that it can be fixed across the whole code-base so that we don&apos;t find it elsewhere.&lt;/p&gt;</comment>
                            <comment id="900658" author="JIRAUSER595019" created="Wed, 20 Jan 2021 23:57:08 +0100"  >&lt;p&gt;You&apos;re probably right. That a null check can be so catastrophic tho...&lt;/p&gt;</comment>
                            <comment id="900596" author="JIRAUSER593813" created="Wed, 20 Jan 2021 22:05:22 +0100"  >&lt;p&gt;This seems to be an issue with locking a weak_ptr. By debugging i&apos;ve found, that the weak_ptr being locked is null, which causes a segfault. Since MSVC and gcc/clang have different implementations of the standard library, it might be related to that. I&apos;ve seen that there is a null-check for a pointer, but only after locking. I believe this would be a simple fix, simply by checking for null before locking the weak_ptr.&lt;/p&gt;</comment>

It might be coincidence and we&apos;ve only played for an hour but we&apos;ve not yet had a crash with this error message since.&lt;/p&gt;</comment>
                            <comment id="898527" author="JIRAUSER476750" created="Mon, 18 Jan 2021 19:54:17 +0100"  >&lt;p&gt;I ended up switching to the Windows version of BDS which doesn&apos;t have this issue. It also seems to run a lot better than the linux version in general (less bugs, chunk load times are much quicker, NPC&apos;s don&apos;t glitch out all the time, and it uses&#160;&lt;em&gt;way&lt;/em&gt; less system resources). This is really unfortunate since I prefer to host the server using docker and not on a VM, but oh well. Hope the Mojang team can fix these issues soon!&lt;/p&gt;</comment>
                            <comment id="897971" author="JIRAUSER597923" created="Sun, 17 Jan 2021 22:57:14 +0100"  >&lt;p&gt;I can confirm that I&apos;m experiencing a very similar issue, my player is in a large village and the server disconnects / crashes within a minute or so of logging in. Journalctl output shows the &lt;font color=&quot;#FF0000&quot;&gt;Village::getBedPOICount[] const (UnknownFile:?)&lt;/font&gt; error line. It does seem like a recent system update could have caused the issue since I had updated very recently.&lt;/p&gt;

&lt;p&gt;So both libs on our 18.04&#160; systems are identical, yet the crash still occurs on my server while your 18.04 seems to work. I&apos;m not&#160;running it in a docker container.&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;

                            <comment id="892478" author="JIRAUSER591766" created="Sat, 9 Jan 2021 08:51:38 +0100"  >&lt;p&gt;I&apos;ve done some more testing using the world files from &lt;a href=&quot;https://bugs.mojang.com/browse/BDS-11039&quot; title=&quot;Server Crashed on Village::getBedPOICount[]&quot; class=&quot;issue-link&quot; data-issue-key=&quot;BDS-11039&quot;&gt;&lt;del&gt;BDS-11039&lt;/del&gt;&lt;/a&gt;&#160;with Ubuntu 18.04 and Ubuntu 20.04.&lt;/p&gt;

&lt;p&gt;With this world I can reliably reproduce the crash under Ubuntu 20.04 following the instructions in that issue (teleport, walk around). That world has lots of villagers present in beds.&lt;/p&gt;

&lt;p&gt;Under Ubuntu 18.04, I cannot reproduce the crash using that world.&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;I don&apos;t believe libc is the issue here - rather, potentially a behavioural change in libstdc+. The stack trace for this crash has std:: in the top few frames, which is provided by&#160;libstdc++ (aka&#160;GNU Standard C++ Library v3).&lt;/p&gt;

&lt;p&gt;libstdc++ versions used in my tests:&lt;/p&gt;

&lt;p&gt;Ubuntu 18.04:&#160;libstdc++.so.6.0.25&lt;/p&gt;

&lt;p&gt;Ubuntu 20.04:&#160;libstdc++.so.6.0.28&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;Can you confirm what libstdc++ version you have present?&lt;/p&gt;</comment>

I&apos;ve just tried with Ubuntu 18.04 (after an apt update/upgrade) and I&apos;ve not been able to reproduce a crash.&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;In summary:&lt;/p&gt;

&lt;p&gt;Ubuntu 21.04 (libc: 2.32): crashes&lt;/p&gt;

&lt;p&gt;Ubuntu 20.04 (libc: 2.31): crashes&lt;/p&gt;

&lt;p&gt;Ubuntu 18.04 (libc: 2.27): working so far&lt;/p&gt;

&lt;p&gt;Please can someone else try using Ubuntu 18.04, confirm libc version and see if they can reproduce the crash.&lt;/p&gt;

&lt;p&gt;confirm libc version with something like:&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;Trying on not up-to-date Ubuntu 18 or similar could be a good test.&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;</comment>

This confirms that this is an issue with the application itself that the developers should be fixing. At least we are not wasting more time with this. I have yet to hear anything back from the support requests as well after many days. &lt;br/&gt;
If the developer doesn&apos;t fix/support the Linux version I will be completely dropping this game all together. I will not trust to move this application to a Windows box and then expose it to internet (not even willing to do it from behind a VPN). My installation in Linux is somewhat hardened to ensure this thing is contained and cannot mess with anything else. In Windows, even on a dedicated box/VM I don&apos;t trust to expose this to internet at all. Windows server is too costly and is too much of a pain to admin, configure, backup, etc... this is just not worth it at all. It&apos;s too bad, they are going to lose several customers (although I don&apos;t really think they care at this point, since they already got their money for Xbox live and the Windows 10 and Xbox clients). &lt;/p&gt;</comment>

&lt;p&gt;Looks like this is specific to the linux server release 1.16.201.2. (at least in my case)&#160;&lt;/p&gt;

&lt;p&gt;I&apos;m checking on my libc version now to see if I can fix the problem with updating libc to the latest.&lt;/p&gt;</comment>

&lt;p&gt;Interestingly if I copy the affected world to a windows 10 system and run as a client world it does not have problems!&#160; &#160;My next step is to try running a windows BDS server with the same world and see if it exhibits the problem.&#160; I&apos;ll keep isolating.&#160;&#160;&lt;/p&gt;</comment>

&lt;blockquote&gt;&lt;p&gt;I am getting the same error and narrowed it down to just being my user that causes it to crash.&lt;/p&gt;&lt;/blockquote&gt;
&lt;p&gt;I managed to repro the issue 10 times in a row in the above ticket using a brand new user (one that had never logged in to that server before), so it&apos;s not related to the specific user.&lt;/p&gt;</comment>

I moved the world to Windows 10 server and it&apos;s working without problems (just a workaround if anyone interested).&lt;/p&gt;

&lt;p&gt;I don&apos;t want to use win 10 just for that. Please fix it.&lt;/p&gt;</comment>

&lt;p&gt;I took the world and loaded it as a local world to my win10 client where it won&apos;t crash but going to where the coordinates are that crash it on the server and I find a lot of quartz blocks missing.&#160; It is making me think the chunk in that area is corrupt.&#160; &#160;&lt;/p&gt;</comment>

I have tried completely removing this off of my server and installing it again, and regardless of navigating away in Windows 10 or not it crashes with this output somewhere between few seconds to a couple of minuets from the time user logs in. I have also tried filling the form to get in touch with support but it has been several days and I have not heard anything back. I suspect they have no customer support at all. &lt;br/&gt;
That server has several other roles and services, so I&apos;m not scrapping or reinstalling the entire Linux server just for this. This program is simply not worth it. If I could get my money back for the clients at this point I would have, and totally scrapped this garbage. We have had to already find something else to do anyways. &lt;/p&gt;</comment>

I was able to find a way to reproduce the bug.&#160;&lt;br/&gt;
Server crashes when i tab out of minecraft on win 10.&#160;&lt;/p&gt;</comment>
