There was a thread on this earlier, but no answer. /var/log/sogo/sogo.log is empty. the last entries in /var/log/sogo/sogo.log.1 show some watchdog errors (processes hanging). This was working yesterday and today isn't.

I did a package upgrade on sogo AFTER it stopped working... didn't resolve it.

/var/run/sogo is writeable by sogo and does create PID files.

Sogo runs, throws its error to syslog (nothing to the console) and exits cleanly according to systemctl.

I'm 100% sure this is something simple relating to either a memory exhaustion or disk space exhaustion issue. Just started exceeding the capacity of this VM, but haven't migrated to something bitter yet.  Didn't know where in the source to look for what file is trying to be opened and is failing.

everytime sogod runs, we get a log entry like this:

sogod: 2022-01-20 13:46:35.937 sogod[696641:696641] unable to get status of descriptor 2 - Bad file descriptor

just starting using sogo with EAS a few weeks ago.

Thanks so much for any suggestions!!
