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:



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?
