The following occured recently on a a heavily loaded 2.2.6 system: ----------------------------------------------------------------------------- Aug 5 22:03:53 ------- /kernel: Fatal trap 12: page fault while in kernel mode Aug 5 22:03:53 ------- /kernel: fault virtual address = 0x4 Aug 5 22:03:53 ------- /kernel: fault code = supervisor write, page not present Aug 5 22:03:53 ------- /kernel: instruction pointer = 0x8:0xf01c089c Aug 5 22:03:53 ------- /kernel: stack pointer = 0x10:0xefbffc70 Aug 5 22:03:53 ------- /kernel: frame pointer = 0x10:0xefbffc9c Aug 5 22:03:53 ------- /kernel: code segment = base 0x0, limit 0xfffff, type 0x1b Aug 5 22:03:53 ------- /kernel: = DPL 0, pres 1, def32 1, gran 1 Aug 5 22:03:53 ------- /kernel: processor eflags = resume, IOPL = 0 Aug 5 22:03:53 ------- /kernel: current process = Idle Aug 5 22:03:53 ------- /kernel: interrupt mask = net tty bio Aug 5 22:03:53 ------- /kernel: panic: page fault Aug 5 22:03:53 ------- /kernel: Aug 5 22:03:53 ------- /kernel: syncing disks...

Can anyone explain to me what happened here and/or tell me how to prevent it from happening again in the future? This sort of event is most annoying.
