I have this problem with one of my production servers, very annoying. 
What I've setup as a workaround is this script that runs every night. To 
be honest, it still sometimes locks up during the day and requires me to 
manually run the scripts, but it's better than restarting the server.

#!/bin/bash
/etc/init.d/kolab-saslauthd stop
/etc/init.d/kolabd stop
/etc/init.d/dirsrv restart
/etc/init.d/kolabd start
/etc/init.d/kolab-saslauthd start

I've upped the file descriptors on this server, but it just delays the 
inevitable. Hope someone figures out a patch soon...
