running on dual quad core intel xeons with 4gb ram.
my server has been rebooting quite a bit and stopped responding today. i found
this on the console:
Fatal trap: 12 page fault while in kernel mode
cpuid = 5; apic id = 05
fault virtual address = 0x0
fault code = supervisor write, page not present
instruction pointer = 0x20:0xc0880472
stack pointer = 0x28:0xe6ea9c8c
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, def32 1, gran 1
processor eflags = resume, IOPL = 0
current process = 12 (idle: cpu5)
trap number = 12
panic: page fault
cpuid = 5
cannot dump. no dump device specified
i've configured the dump device and will follow the kernel debugging details in
the handbook if it happens again but i thought i'd write in now in case the
cause of the problem jumped out at anyone.
i've run mprime for 24 hours, and memtest for 3 passes, and a script i
wrote which just exhausts ram and CPU, then backs off and does it again
which have been running for 24 hours.
i've also just started running this:
i noticed that the same "fatal trap 12" appeared during stress tests as
any help, guidance or information would be much appreciated.
