He's currently running 2.2.2-RELEASE (I know we should upgrade, which we're trying to do, but the problem we're experiencing is preventing that from happening). The problem is that the machine would spontaneously reboot without warning. He and another friend of his finally got some remote logging set up, and this is what they found the last time it rebooted: Fatal trap 12: page fault while in kernel mode fault virtual address = 0xd fault code = supervisor write, page not present instruction pointer = 0x8:0xf0129e32 stack pointer = 0x10:0xefbffdfc frame pointer = 0x10:0xefbffe04 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 25263 (make) interrupt mask = bio panic: page fault syncing disks... 76 76 76 76 76 76 76 76 76 76 76 76 76 76 76 76 76 76 76 76 giving up Automatic reboot in 15 seconds - press a key on the console to abort Rebooting... In this particular instance, it rebooted during the "make buildworld" process. However, it doesn't seem to make a different what process is running at the time. At first we thought it was memory, but we swapped out the memory (it has 128 MB) and it still had problems. Then we became suspicious of the swap drive, thinking perhaps it had a bad spot on it somewhere. However, on the last crash, he was monitoring it, and it hadn't even dipped into swap yet (at least it hadn't appeared to... maybe it did and that's what caused the reboot... don't know). We've noticed before that in, say, compiling a kernel, it will almost invariably fail the first time (but won't crash the machine). Then, if you do "make" again on the kernel, it'll pick up where it left off and finish successfully. Obviously, I don't like seeing that, because that tells me something is definitely wrong. Given the output above, does anyone have any theories as to what the problem might be?
