Not quite, though my machine crashed a couple of times a few weeks ago
because my CERN httpd proxy (which had been running happily for over a
year) decided to fork itself to death.  After the 2nd crash I saw what
was going on and set a ulimit on its processes, so it would fork 40
times and then say it couldn't contact the host.

I've been running without the proxy ever since - I don't have time to
debug it just now. 

FYI

-r-x--x--x  3 root  wheel  2591691 Aug  7  1995 /httpd/httpd_cern*
-rwxr-xr-x  2 root  wheel   925668 Feb  7  1996 /netbsd*

this is generally a very stable machine and I'm not aware of any
changes that would/should have affected httpd_cern.

The only problems I have are named occasionally getting into a state
where it simply fails to resolve anything, and running out of swap.
Both problems are resolved by daily re-starting named and all the http
servers.
