I have a fairly recent 8-stable machine running under VMWare ESXi 3.5
(amd64 guest), which apparently crashes every few days from the same causes:
em0: discard frame w/o packet header
em0: discard frame w/o packet header
em0: discard frame w/o packet header
Panic string: sbsndptr: sockbuf 0xffffff007cca8c20 and mbuf
0xffffff00490a6400 clashing
More information available here:

The crash looks like is provoked by ssh bruteforce attack attempts, some
of which are blocked by an ipfw-based blocker.
Any ideas?
The machine was previously (until a month ago) running 7.2-RELEASE
without these panics.
