freebsd stable - Apr 2006 - "no more processes"

Just had a box go unresponsive on all services (still pingable) had a session 
still open to it but any command would result in the error "no more
processes"
Checks clean for a rootkit and nothing amiss in the logs (that I can find).
I have never heard of a bsd box giving this error before, I can't even think
of
what (other than a hack) would cause such an ungraceful freeze.

Any suggestions welcome.

Something went crazy spawning processes (either quickly or over a long
time).  Break to DDB to find out what processes are running, or if you
have another session still open with processes running, try to kill
them to make more space and then immediately run top.
