I don't know about limits.conf, it seems to take effect only, when you 
login via PAM, but I run "ulimit -n unlimited" in init.d script of 
dovecot. Do you have some process hardening stuff running, e.g. AppArmour 
or SELinux? They seem to interfere with anything :-)

The why you have to determine on your server. How many file descriptors 
are in use by the processes and what they are connected to? Can you 
reproduce the crash easily?
