Hello,
we have the following problem:
Nov 3 09:43:33 minerva dovecot: [ID 583609 local0.warning] master: Warning: service(anvil): client_limit reached, client connections are being dropped Nov 3 09:51:33 minerva dovecot: [ID 583609 local0.error] imap-login: Error: net_connect_unix(anvil) failed: Connection refused Nov 3 09:51:33 minerva dovecot: [ID 583609 local0.crit] imap-login: Fatal: Couldn't connect to anvil Nov 3 09:52:42 minerva dovecot: [ID 583609 local0.error] pop3-login: Error: net_connect_unix(anvil) failed: Connection refused Nov 3 09:52:42 minerva dovecot: [ID 583609 local0.crit] pop3-login: Fatal: Couldn't connect to anvil Nov 3 09:52:42 minerva dovecot: [ID 583609 local0.error] imap-login: Error: net_connect_unix(anvil) failed: Connection refused Nov 3 09:52:42 minerva dovecot: [ID 583609 local0.crit] imap-login: Fatal: Couldn't connect to anvil
At that time I counted 2030 imap processes from 995 users and 1106 imap-login processes. What can I do to set an appropriate client_limit for anvil?
The configuration is:
# doveadm config -n
# 2.0.5: /opt/local/etc/dovecot/dovecot.conf
# OS: SunOS 5.10 sun4v
