[Kolab-devel] kolab-saslauthd crashes

I just wanted to follow up on this issue. It would appear that the 
dirsrv service seems to "run out" of fds and shuts down until the dirsrv 
is restarted. I've managed to increase the number of open fds from 1024 
to 8000something which effectively reduces the crashes to once a week 
instead of once a day, but just to make sure I've set up a cron with the 
following script to run once a day every night, obviously not ideal.

/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

If someone else has a better idea/solution, please let me know.
