I forgot to add that I also upgraded from 1.1.1 to 1.1.3 yesterday in
an attempt to fix the problem.

Hi,
I'm running Dovecot 1.1.3 on FreeBSD 7.0. In the past couple
days, I've been seeing errors like this:
Sep 9 08:43:51 sysvol dovecot: pop3-login: socketpair() failed: No
buffer space available
Sep 9 08:43:51 sysvol dovecot: pop3-login: socket(default) failed:
No buffer space available
Sep 9 08:43:51 sysvol dovecot: pop3-login: Can't connect to auth
server at default: No buffer space available
Sep 9 08:25:15 sysvol dovecot: pop3-login: socketpair() failed: No
buffer space available
pop3-login: Can't connect to auth server at default: No buffer space
available
What ends up happening is that the port doesn't accept any new
connections until there is enough buffer space.
Yesterday, I saw it a LOT with POP3 and changed my config login
processes:
login_process_per_connection: no
login_process_size: 256
login_processes_count: 6
This seemed to clear up the issues, but now it's occurring again
this morning.
I haven't had any of these since I made that change either.. So
there's some progress... :
Sep 8 12:53:40 sysvol dovecot: Temporary failure in creating login
processes, slowing down for now
TOP shows:
Mem: 267M Active, 5558M Inact, 1637M Wired, 217M Cache, 214M Buf,
87M Free
Swap: 4096M Total, 4096M Free
At this time, there are 120 imap processes, 10 POP and 1 dovecot and
1 dovecot-auth
pop and imap both have 6 login processes. It doesn't seem like a
load issue, but obviously something is set too low or unavailable...
It's fixed for a period of time when I restart dovecot. I did a
netstat -m prior to restart, and after restart, and the only main
difference was this line:
Before:
11/414/425/12800 4k (page size) jumbo clusters in use (current/cache/
total/max)
After:
0/425/425/12800 4k (page size) jumbo clusters in use (current/cache/
total/max)
(After about 5 minutes 'current' went to 3)
This machine also runs NFSd and MySQL.
Any ideas?
Thanks,
Rick
