RE: about imap-login: Error and imap: Error after Version-UP

Hi.. 

there is supposed to be only at most one (1) stats process. Having multiple 
stats processes breaks stats.

Aki-san

Last night We adjusted the "process_limit" in the stats service to get rid of 
the error.

"client_limit" is in the blank (default) state.

Thank you very much.

You need to configure stats service client limit and imap service client limit. 
Those are different services than imap-login service.

You need to configure stats service client limit and imap service client limit. 
Those are different services than imap-login service.

I have already seen that page.
Is the setting method wrong?

Is there any other tuning point?

about imap-login: Error and imap: Error after Version-UP

2020-11-16 Thread 森川 孝司
We have upgraded dovecot from 2.0.9 (centos6) to 2.2.36 (centos8).

If more than 1000 users log in, the following error will occur.
-
Nov 16 11:33:00  dovecot[1361]: imap-login: Error: master(imap):
net_connect_unix(imap) failed: Resource temporarily unavailable -
http://wiki2.dovecot.org/SocketUnavailable (client-pid=1362,
client-id=129834, rip=10.10.10.10, created 551 msecs ago, received 0/4
bytes)
Nov 16 11:30:26  dovecot[1361]: imap: Error:
net_connect_unix(/var/run/dovecot/stats-writer) failed: Resource temporarily
unavailable
-

I set the following because I thought it was a problem with the number of
connections, but I get an error.

service imap-login {
  service_count=0
  client_limit = $default_client_limit
  process_min_avail = 4
  process_limit = $default_process_limit
  vsz_limit = 1G
}

limits.conf
-
* soft nofile 4096
* hard nofile 4096
-

cat /proc/sys/net/core/somaxconn
-
4096
-

Is there any other tuning point?
Where should I look?
