Hello, Im using dovecot for ages and im happy.. but at now strange things happens:
mutt returns: Error talking to localhost (Connection reset by peer)
so i started telnet: alnagon ~ % telnet localhost 143 Trying 127.0.0.1... Connected to alnagon.localnet.cz. Escape character is '^]'.
- OK Dovecot ready. 1 login karpi blablabla 1 OK Logged in. Connection closed by foreign host.
Last line "Connection closed" appears immediatelly after logging..
log says: Oct 27 11:20:50 alnagon dovecot: imap-login: Login: user=<karpi>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Oct 27 11:20:51 alnagon dovecot: IMAP(karpi): setuid(1000) failed: Resource temporarily unavailable Oct 27 11:20:51 alnagon dovecot: child 8537 (imap) returned error 89

setuid(2) says:
EAGAIN The uid does not match the current uid and uid brings process
over its RLIMIT_NPROC resource limit.So you've somewhere limited the number of processes for users. Debian has them in /etc/security/limits.conf. I'm not exactly sure what reads that file and how those limits are passed to kernel.
Thank you Timo, that's the ticket! I was running too much processess (>300) so i shut down some consuming applications, and dovecot runs ok. Now i will tune my system setting in /etc/security/limits.conf
thanks again.. 27/10/07 17:11, tss@iki.fi napsal(a):

The file is read and applied by pam_limits.so, which tells the kernel about the limits with setrlimit(2).
