Hi, other error in "open files":

This comes from the dovecot master process.

open files (-n) 1024

And it's limited by this.

Now, we have this: # lsof -p cat /var/run/dovecot/master.pid | wc -l 1018

So increase ulimit -n before starting Dovecot.

What Dovecot version are you using? If v1.1+, doesn't it give a warning at startup that your limit is too low?
