Hi. Days ago I sent a message to this list asking for help on a problem that seemed to me to be old: dovecot hangs and dovecot-auth posts log messages like: Nov 16 17:04:39 netuno dovecot: imap-login: Can't connect to auth server at default: Resource temporarily unavailable Nov 16 17:04:42 netuno dovecot: pop3-login: Can't connect to auth server at default: Resource temporarily unavailable Unfortunatelly when this happens the only way to recover is to restart dovecot. After I while I begun to clean the dovecot-auth processes (defunct or not) that remain in the process list and the cycle of running/hunging restart from 1 hang a day until it reaches 1 hang each 10 minutes, when I kill dovecot-auth again. I've seen some days ago some messages related to this problem but they were inconclusive, meaning that they didn't point to a solution. Any help is welcome. Thanks. Ricardo
