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
Only thing I can suggest is to google for "ENOBUFS socketpair freebsd"
or to ask in FreeBSD lists. I've no idea why it would return ENOBUFS.
The manual page doesn't say ENOBUFS is a possible error for
socketpair().
Got it. Thanks Timo, your search terms were better than mine.
sysvol# vmstat -z | grep sock

My old kern.ipc.maxsockets: 12328 I was running out of Sockets.
The error was popping up multiple times per minute, now I haven't seen
one in 5 minutes.
I also found a great FreeBSD connection optimization page:
