I've had this one server crash about once every 1-2 months now for the last 5 months. The kernel is not compiled with debugging symbols (sorry) but the backtrace is probably better than nothing, at least it tells me where to start looking. I found a couple of vague references to this but nothing really helpful. This last crash happened right when I ran pkgdb -F (althoug= h there were other things happening as well). I have not run fsck in single user mode throughout all the crashes. I'm thinking that might be a good idea and might possibly fix whatever disk problem is present?
