AOL Me too!
Except this happens with 1.4.1 on pentium 200MHz with ~90MB
memory and two Cogent cards (de0, de1). 

This is a bit problematic because I run gobs of mrtg processes and
NAT (cough!) and the mrtg-processes stay in the run que and in
the morning I might have something like >1000 processes.
Reboot helps but I'd say that's a suboptimal solution.
I've added MAXUSERS and pumped up NMBCLUSTERS which seems to have
helped.
