Red Hat Bugzilla – Bug 7219
Linux reboots during heavy disk usage
Last modified: 2008-05-01 11:37:53 EDT
Linux reboots itself during operations that require large volumes of database writes to the disks, such as ORACLE imports and data loading. We have a adaptec 2940 ultrawide scsi host adaptor with 5 * 4GB disks. Therefore, this may be related to bug number 2938; but we have a slightly different hardware configuration (including a pentium processor). We have checked for bad memory using memtest86 and there's no problem there. Before we recompile the kernel, could you give us any further information or a suitable resolution for this problem. The reporter of bug 2938 found his own resolution to the problem of Linux 'spontaneously' rebooting, but he says he's not 'absolutley certain' of the cause of the problem and seems to have changed several settings in the kernel.

Re-compiled the kernel with APM and watchdog timer removed, and using 386 instead of 586 optimisations. This has not resolved the problem!!! The machine is still consistently crashing during heavy disk usage.
This might be totally left field... but I've had similar problems (with M$ systems) that turned out to be Power Supply Problems...

has this been resolved with newer kernels/releases
