A kernel panic occurred today on a machine with an uptime of about 5 days. Console output including a stack trace is below. I was not able to obtain a core dump after this panic. The machine froze when I attempted to generate a code dump and had to be power cycled. The machine acts as a NAT device and was carrying user traffic at the time of the panic. I have conducted load tests of an identical machine in a test environment and I have not been able to reproduce this kernel panic. We've been running 8.0p1 in this set up on multiple machines for a couple of months. This is the first kernel panic of this type we've seen.
