Hi,
I recently had 3 kernel crashes on 2 different
machines in the same place. The machines have 3 GB
memory (but MAXMEM is set to 1 GB in kernel config
file). The machines are running freeBSD 4.4, Sept 16th
build. Enlcosed is the trace of the crash...

Uptime: 7m6s
I was looking at the core and it the dvp->v_mount
field in frame 6 is corrupted. Haven't seen this b4,
but its quite puzzling to see 3 crashes. Also, the
uptime shows that it happened very quicky.
any ideas whats goin on here ??
thanks
nitin
