Server is crashing during world backup (Watching Server)

[CityAplons]

Hi,
We faced several times with server crashes during world backup.
There is no helpful information in the crash log. Watchdog is just killing it.

Server specs: 4 core 2.2GHz, 8Gb RAM, Ubuntu 20.04, OpenJDK 17 java package.
Log: https://pastebin.com/tw4p6bac

Probably, the reason is an old migrated world. However, several weeks ago, the server made backups successfully. Is it possible to check or fix world errors?

Hm, a textile backup shouldn't be able to lock up the server for long enough to trigger the watchdog, but if your world is very very big I'm sure that's a possibility.
I would suggest trying to edit the watchdog timeout in server.properties, the value is called "max-tick-time" and is set to 60000 by default (milliseconds).

Well, the problem stays in place. 😑 Is there any way to profile or debug the server backup procedure?

Another log, if it can help.
