Dovecot stops alone

1

Good morning!
I have dovecot with the default hestiacp configuration with debian 12

Lately the dovecot service stops by itself and I have looked at the logs and apparently it does not indicate the error.

Any idea to prevent this from happening?

Thanks

Hi @servtelecom

It should show something.

Check again:

systemctl status dovecot --no-pager -l
journalctl -u dovecot --no-pager -l
grep -i dovecot /var/log/syslog
tail /var/log/exim4/paniclog

Also check disk and memory:

df -h
free -m

I don’t see any errors, just this in case it could be the cause:

doveconf: Warning: NOTE: You can get a new clean config file with: doveconf -Pn > dovecot-new.conf

I copied the entire dovecot directory from another installation that works correctly, let’s see if it doesn’t fail again. For the moment, the previous error is no longer mentioned in the log if I restart the dovecot service

I’ll let a few days go by to see if it doesn’t fail!

What I don’t know is if there is any parameter in Dovecot that can increase RAM and CPU consumption in case the problem is that it is too low and that is why it stops. There are several domains and users that consult this server.

I have added the following

service imap {
vsz_limit = 512M
process_limit = 1024
}

Let’s see if that improves
