Then I grabbed the 2.2-STABLE release and tried again. I also set maxusers 50 in the kernel config just in case. The machine is our mail, dns, and authentication server for radius. Although it has no user shell accounts it can still get quite busy with many sendmails and perl scripts running at once. Any suggestions are welcome. - Ernie.
