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)
