I'm just having bizare problems. I have 2 frontends and 1 backend in a murder
configuration. If I have ANY kind of mail load incoming then the whole system
craps out (under what I'd consider very light load actually). I currently have
1 frontend setup to accept pop and imap connection and the other frontend
running sendmail and delivering mail via lmtp. If I turn on sendmail, then all
of a sudden my pop login times exceed 30 seconds. I'm quite at a loss. I don't
know if it's a frontend problem or a backend problem.
Here is my frontend imapd.conf:

Neither the backend or the frontend(s) are overloaded and the strace stuck on
socketmap is the only thing I've been able to find to explain why pop logins
take 30-60 seconds if there's incoming email. There are approximately 26,000
accounts on the backend.
Help :( I'm at wits end. Thank you.

I have a a MURDER setup and I notice that if the frontends are
getting any type
of mail load that sendmail takes over 30 seconds to send a small message
(sometimes over a minute). So I've picked a few "stuck" sendmails
and strace'd
them.
The strace just sits at the following:
Process 9991 attached - interrupt to quit
connect(6, {sa_family=AF_FILE, path="/var/lib/imap/socket/socketmap"}, 110
So it looks like my entire bottleneck has to do with socketmap
somehow. Is there
anyway I can speed things up? Thanks.
1) How long does it take to to query cyrus from "sendmail -bt" ?
echo "/map cyrus user" | sendmail -bt -d60.5 -d38.20
2) Could you post smmapd entry from you cyrus.conf file ?
3) Could you post "cyrus user limits" ?
as cyrus user execute "ulimit -a"
