Hello
I have this messages in log: Jul 29 00:02:56 10.0.4.16 dovecot: imap-login: Can\'t connect to auth server at default: Resource temporarily unavailable Jul 29 00:02:56 10.0.4.16 last message repeated 6 times Jul 29 00:02:56 10.0.4.16 dovecot: pop3-login: Can\'t connect to auth server at default: Resource temporarily unavailable Jul 29 00:02:56 10.0.4.16 last message repeated 6 times Jul 29 00:02:56 10.0.4.16 dovecot: imap-login: Can\'t connect to auth server at default: Resource temporarily unavailable Jul 29 00:02:56 10.0.4.16 last message repeated 15 times Jul 29 00:02:56 10.0.4.16 dovecot: pop3-login: Can\'t connect to auth server at default: Resource temporarily unavailable
In this way users can't connect top pop3, imap services. Dovecot restart only help me to restore my services. I have 80k users and ~250k sessions per day. i thank you very much for any valid hint.
Debian Linux 2.6.18-4-686
