Yesterday I faced a problem that the service pmg-smtp-filter stopped abnormaly:

Code: 
Nov 26 13:07:56 gateway systemd[1]: pmg-smtp-filter.service: Main process exited, code=exited, status=11/n/a
Nov 26 13:07:56 gateway systemd[1]: pmg-smtp-filter.service: Killing process 5291 (pmg-smtp-filter) with signal SIGKILL.
Nov 26 13:07:56 gateway systemd[1]: pmg-smtp-filter.service: Killing process 5309 (pmg-smtp-filter) with signal SIGKILL.
Nov 26 13:07:57 gateway systemd[1]: pmg-smtp-filter.service: Failed with result 'exit-code'.

I looked at syslog but I didn't find nothing that showed something that hinted why this happened. The service remained like that for some time and I had to manually start again to everything work normally. What I can do to avoid this to happen again? Thanks!
 
If possible please share the complete journal around the time the problem occured - from the 4 lines it's impossible to see what might have caused the issue.

Thanks!
 
Around this time I can see this error syncronizing with the cluster, then the process exited.

How much memory/RAM does the PMG have?
(The messages from ClamAV make mit think it might be an OOM condition)
