            <title>[BDS-9286] Bedrock Server will start consuming exponentially much RAM when using high slot amounts</title>
                <link>https://bugs.mojang.com/browse/BDS-9286</link>
                <project id="11700" key="BDS">Bedrock Dedicated Server</project>
                    <description>&lt;p&gt;&lt;span class=&quot;image-wrap&quot; style=&quot;&quot;&gt;&lt;img src=&quot;https://bugs.mojang.com/secure/attachment/340712/340712_image-2020-10-07-19-05-04-743.png&quot; style=&quot;border: 0px solid black&quot; /&gt;&lt;/span&gt;&lt;/p&gt;

&lt;p&gt;This was with a slot limit of&#160;700000. 5.7GB ram usage. Crashes are rather random at these high numbers, and I managed to get it to crash at even only 600000 too, so yea. It should definitely be fixed and made so slot amount really is just a number and not a performance indicator.&lt;/p&gt;</description>

                            <comment id="824647" author="ionicecko" created="Tue, 13 Oct 2020 16:13:03 +0200"  >&lt;p&gt;Hi Jorge,&lt;/p&gt;

&lt;p&gt;Based on the how-to document this would appear to be expected behavior, excerpt below.&lt;/p&gt;

&lt;blockquote&gt;
&lt;p&gt;max-players	Any integer	10	Always	The maximum numbers of players that should be able to play on the server. &lt;b&gt;Higher values have performance impact.&lt;/b&gt;&lt;/p&gt;&lt;/blockquote&gt;</comment>
                            <comment id="824644" author="JIRAUSER557965" created="Tue, 13 Oct 2020 16:07:37 +0200"  >&lt;h4&gt;&lt;a name=&quot;Summary&quot;&gt;&lt;/a&gt;Summary&lt;/h4&gt;

&lt;p&gt;The server uses tons of RAM when using high slots&lt;/p&gt;
&lt;h4&gt;&lt;a name=&quot;Stepstoreproduce...&quot;&gt;&lt;/a&gt;Steps to reproduce...&lt;/h4&gt;
&lt;ol&gt;
	&lt;li&gt;Set slots to&#160;600000 (or any other high value, maybe lower / higher) in server.properties&lt;/li&gt;
	&lt;li&gt;Run server&lt;/li&gt;
	&lt;li&gt;Check RAM usage&lt;/li&gt;
&lt;/ol&gt;


&lt;h4&gt;&lt;a name=&quot;WhatIexpectedtohappen...&quot;&gt;&lt;/a&gt;What I expected to happen...&lt;/h4&gt;

&lt;p&gt;Server uses same RAM amount independent on slot amount (like in java)&lt;/p&gt;
&lt;h4&gt;&lt;a name=&quot;Whatactuallyhappened...&quot;&gt;&lt;/a&gt;What actually happened...&lt;/h4&gt;

&lt;p&gt;Server RAM either depends on slot amount, or it simply can&apos;t handle the slots and freaks out, using way too much RAM compared to normal slot amounts like 50&lt;/p&gt;</comment>
                            <comment id="824614" author="ionicecko" created="Tue, 13 Oct 2020 15:37:17 +0200"  >&lt;p&gt;Can you please elaborate on the problem and include steps to reproduce.&lt;/p&gt;

&lt;p&gt;Are you saying that merely adding high slots and starting the server will immediately result in high RAM utilisation?&lt;/p&gt;

&lt;p&gt;Please use the template below which helps include the information volunteers need to reproduce your issue:&lt;/p&gt;
&lt;blockquote&gt;
&lt;h4&gt;&lt;a name=&quot;Summary&quot;&gt;&lt;/a&gt;Summary&lt;/h4&gt;
&lt;p&gt;This is a brief summary of what happens&lt;/p&gt;

&lt;h4&gt;&lt;a name=&quot;Stepstoreproduce...&quot;&gt;&lt;/a&gt;Steps to reproduce...&lt;/h4&gt;
&lt;ol&gt;
	&lt;li&gt;Set X in server.properties&lt;/li&gt;
	&lt;li&gt;Run server&lt;/li&gt;
	&lt;li&gt;Connect to server and chop tree&lt;/li&gt;
	&lt;li&gt;GUI goes rainbow&lt;/li&gt;
&lt;/ol&gt;


&lt;h4&gt;&lt;a name=&quot;WhatIexpectedtohappen...&quot;&gt;&lt;/a&gt;What I expected to happen...&lt;/h4&gt;
&lt;p&gt;What did you expect to happen when performing said steps (sometimes this is obvious as it may be in this case)&lt;/p&gt;

&lt;h4&gt;&lt;a name=&quot;Whatactuallyhappened...&quot;&gt;&lt;/a&gt;What actually happened...&lt;/h4&gt;
&lt;p&gt;What did you see/experience&lt;/p&gt;&lt;/blockquote&gt;</comment>
