[Dovecot] Resource temporarily unavailable
On very high traffic in POP3 I have flood of messages in my log:
Feb 2 16:32:17 pp4 dovecot: pop3: Error: net_connect_unix(/var/run/dovecot/auth-master) failed: Resource temporarily unavailable
What a Terrible Failure (WTF)?
Can You help me resolve this problem? I've not found any info about auth-master problem :/
My settings: default_process_limit = 2000 default_client_limit = 4096
service pop3-login { service_count = 0 vsz_limit = 128M process_min_avail = 8 }
FD limit in system = 32000 8 cpu, 28GB RAM about 50 login per second
Different Error messages I've when set service_count = 1. Feb 2 10:21:29 pp4 dovecot: pop3-login: (5052) Disconnected: Connection queue full (no auth attempts)

auth process isn't responding fast enough.
My settings:
Full doveconf -n output please.

That's expected. If you set service_count=1 you need to increase the process_limit.
