I have several jails running on my freebesd machine and lately it started to
crash when it gets a bit loaded. I followed the freebsd kernel debugging
manual, and got some output, but I have no idea what to do with it. The only
thing I think I understand of it that the bit that matters are just the two
last lines. Is there anyone that can help?
