Has this happened more than once?
In this way users can't connect top pop3, imap services. Dovecot
restart only help me to restore my services.
How long did it happen until you restarted?
It sounds like dovecot-auth process got stuck for some reason. If it
happens again, you could:
Run strace -p
pidof dovecot-authfor a few seconds and save the
output (if you have multiple dovecot-auth processes, then strace the
one which doesn't have -w parameter)Run gdb -p
pidof dovecot-auth(again the process without -w) and
"bt full" after that.
passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf
What SQL database are you using?
