Hi:
We have a RHEL 4 machine which is used as a software
testing machine. Today, we did some stress test on a
software that we are develooping. The machine seems to
crash repeatedly during the process of testing.
During a crash, I was able to copy the content of the
screen. The following were displayed on the screen.
eax : 00067a92 ebx:c3fd000 (plus other register values)
process swapper (pid 0, threadinfo=c03ce00 task=c0322980)
stack : 00002456 c03c3fcc (and presumably some address)
c0126968
Call Trace
[<c01269b8>] __do_softirq + 0x4c/0xb1
[<........>] do_softirq
------------------------------------------
------------------------------------------
[<........>] smp_apic_times_interrupt
[<........>] apic_times_interrupt
[<........>] mwait_idle
[<........>] cpu_idle
[<........>] start_kernel
code : <hexadecimals...>
It is a kernel panic/crash, right? I was wondering if
the crash was related to the program (it didn't core dump
even after setting ulimit -c <large number>)
Is it possible for a software to crash a kernel? If
there's a bug, the program should have produce a
segmentation fault and exit without affecting the kernel.
Is there a way of knowing if the kernel panic is
caused by a flaky hardware or is caused by a buggy
software?
I'm trying to make sure it is not the kernel per se
that causes the crash by downloading the latest kernel.
Any ideas? Thanks in advance.
