[Dovecot] 1.0alpha1: too many open files
Help...
Dovecot 1.0alpha1 hung up today with nothing working and the following spewing to my syslog:
pipe() failed: Too many open files
My setup: Solaris 9, just using imap, mbox format. The various "max" settings in dovecot.conf use the defaults. Suggestions on what to change in fovecot.conf to keep this from happening?

I found this:
echo "4096" > /proc/sys/kernel/file-maxFirst cat /proc/sys/kernel/file-max to see what it's set to.

Actually on Solaris 9 you want to put something like this in /etc/system:
set rlim_fd_cur = 32768 set rlim_fd_max = 65536
That sets the current fd's to 32k and max to 64k. Unfortunately, to take effect you'll need to reboot. After the reboot, ulimit -a should show that nofiles(descriptors) is 32768.

If this happens again, check how many imap, imap-login and dovecot-auth processes are running. Can you check with Solaris 9 what fds are open for a process (for dovecot master process)? Looks like with Solaris 10 I can at least see from /proc/pid/fd/ if the fds are pipes, sockets or files.
