It sounds like dovecot-auth process got stuck for some reason. If it happens again, you could: 1) Run strace -p `pidof dovecot-auth` for a few seconds and save the output (if you have multiple dovecot-auth processes, then strace the one which doesn't have -w parameter) 2) 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?
