Hi,
Since the below happened at logrotation-time, I checked that out that a
bit more carefully of the server, and discovered a difference between
stretch <-> buster logrotate config.
As I manually edited our /etc/logrotate.d/rsyslog, the dist-upgrade had
not replaced our file. See
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=900586
I hope this has an effect on the observed SOGo behaviour.
I will update this next week sunday, to let the archives know if it
helped. Still strange that it results segfaults in sogo.
Regards,
MJ

Hi,
We are running sogo (5.0.1-1) on an upgraded stretch -> buster debian
x64. We've noticed serieus looking issues on two saterday nights in a
row, when cron restarts sogo (I guess after log rotation)
It starts off with some segfaults:
Nov 15 00:00:27 server kernel: [552373.802573] sogod[23629]: segfault
at 7ffe84ab0583 ip 00007f9e51069201 sp 00007ffe04ab0488 error 4 in

0f 10 7c 16 d0 44 0f 10 44 16 c0 49
next sogo is stopped:
Nov 15 00:00:27 server sogo[2019]: Stopping SOGo: sogo.
Nov 15 00:00:27 server systemd[1]: sogo.service: Succeeded.
Nov 15 00:00:27 server systemd[1]: Stopped LSB: SOGo server.
Nov 15 00:00:27 server systemd[1]: sogo.service: Found left-over
process 23446 (sogod) in control group while starting unit. Ignoring.
Nov 15 00:00:27 server systemd[1]: This usually indicates unclean
termination of a previous run, or service implementation deficiencies.
and the sogo restart:
Nov 15 00:00:27 server systemd[1]: Starting LSB: SOGo server...
However this last start fails, and SOGo is no longer running after the
above.
Full syslogs logs are here:

I think the sogo.service that is used is a generated one, here:
root@server:/proc/1# cat /run/systemd/generator.late/sogo.service

Anyone with an idea?
