Zabbix Server Crash Loop

[AndyFug]

Hi,
We have been running Zabbix 7.0.6 in Docker for several weeks without issue after a successful upgrade from 6.4. We are using TimescaleDB. Our VMs were rebooted a couple of times in the last couple of days and unfortunately ever since one of those reboots, our Zabbix Server container has been in a constant crash cycle. After reading the Zabbix forums, I tried updating to 7.0.8 and then subsequently 7.2.3. Unfortunately none of the updates changed the crash behaviour. Here is a snippet from the logs just before the crash (debug level 5).

It appears to be something to do with the process

In DCsync_interfaces()

I would attach a copy of the log file, but it is not allowing me to upload them due to the file size. Any help diagnosing the issue and resolving it would be great.

Many thanks.
