 Description   

Seems there is an issue with making backups after this last update.

I have some match files that make back ups, a daily back up and hourly back ups.

The batch works as follows.

  1. Issue "save hold"
  2. Wait 15 secs
  3. Copies world to back up folder
  4. Issue "save resume"

The previous version of BDS this ran without any issues.

Since the update (no changes made to the batch scripts). However we seem to hang after the save hold. We have disabled the schedule backups and just tried running manually to rule out the scripts and we got hung after the save hold was issued. Please let me know if you need any more details.

Hi Foxy/Alfred,

Just wanted to confirm, does this happen even when not touching any files?

I know at the moment there's the issue with the manifest and log file being locked on Windows so was curious if this can just be repro'd by running save hold, save query and save resume at regular intervals without actually interacting with the files.

Figured it was worth asking before I spend time trying to repro.

Today we ran for a good 12 hours autosaving regularly without any crashes / hangs.
The server was intentionally restarted twice in during that time (Auto restart every 5 hrs).
After the 2nd restart one of the saves triggered the freeze which then continued to happen every 2 or 3 saves (autosave every 10 mins).

It's strange that we had so much time without an issue with people playing and then once we encountered it it continued to happen, even after restarting the BDS.
The BDS was started that morning on a fresh boot of the server PC.
I wonder if this issue is a memory leak or something that builds up over time.

According to task manager, the bedrock_server.exe is only using 300MB of ram on a 16GB system which is only using 20% for all processes.

I confirm this is an issue for me too.

Not after every backup. Sometimes it can go through several successful backups which are automated every 10 mins.

The more players online the more often it hangs.

For me, I am not waiting 15 seconds after save hold, (only 2 seconds) and it is hanging either mid save (prior to save resume) or just after the successful save finishes.
So I theorise from the main bug report, that the issue is happening at a specific time after the save hold call rather than on the call.

Today I played for 2 hours saving every 10 mins without issue. I was the only one online.
Yesterday with 3 of us it crashed every 2nd or 3rd save.

No crash report . The server just becomes unresponsive.

This is running on Windows 10 Pro
