Could either of you give some more data, like the configurations
of your system, the type of network that you're using, the client
that the Apache bench program is run on (i.e. how fast is it), and
the size of the file that is being transferred with each request?
And perhaps the types of ethernet card that you are using.

I've tried to reproduce it, but so far without success. The mbuf
allocation code did give me the usual "WARNING: mclpool limit reached;
increase NMBCLUSTERS" (I had put nmbclusters at 4096), but no crash.
This was with the server on a PIII-450, with the client on a P5-133,
talking to eachother over a 3com 905B and an i82558. I also
tried using localhost on the PIII-450, still no crash.

I'd love to reproduce and fix it, because it's a serious bug that
has been plagueing people using 1.4 or later a lot.
