Hi, Now I managed to get a kernel dump. I even got two of them, with different panic, both page fault, one on read, one on write. The machine had been runing fine for a year when it started to panic on heavly load. I updated the kernel but not to avail. I tried all the hardware monitoring in usr/ports/sysutil but none could report CPU temperature for that Asus CUR-DLS motherboard. I do suspect a temperature problem because when I kept the rack drawer open it it not panic. What should I do next? Fatal trap 12: page fault while in kernel mode mp_lock = 00000002; cpuid = 0; lapic.id = 03000000 fault virtual address = 0x38053bc0 fault code = supervisor write, page not present instruction pointer = 0x8:0xc01d2ae5 stack pointer = 0x10:0xcd66ad04 frame pointer = 0x10:0xcd66ad14 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 = 688 (dumper) interrupt mask = bio <- SMP: XXX trap number = 12 panic: page fault mp_lock = 00000002; cpuid = 0; lapic.id = 03000000 boot() called on cpu#0 Best regards, Olivier
