This sounds like you are running out of mbuf clusters. Watch the amount in- use closely with netstat -m. On a busy WWW server, you should add: options "NMBCLUSTERS=4096" ...to your kernel config file to avoid running out of them. The default calculation is based on maxusers and is intended for general purpose use of which a WWW server is not. >It is running 2.2-032396 SNAP.

You really should be running 2.1-stable on this machine. -current is for developers and is known to be unstable. -DG David Greenman Core-team/Principal Architect, The FreeBSD Project
