Fatal Trap 12: page fault while in kernel mode on IBM x340 after Aug25CVS
Hi,
We did an upgrade of one of our machines from an Aug 25 CVS and ever since
then one of the machines likes to reboot about once a day.
The machine is the following:
IBM x340
2x1GHZ Processors
1GB RAM
3x36GB Drives (RAID 5)
Mylex ExtreRAID 352
In the panic it mentions httpd, but I don't *think* it's apache (1.3.27)
that's causing the problem, or am I wrong? I also believe it is not a load
issue as the load does not get much about 2 most of the time.
The only special kernel config is that it's an SMP kernel and the following
options are set:
options NMBCLUSTERS=20000
options PMAP_SHPGPERPROC=600
options IPFIREWALL
options DUMMYNET
Below is a copy of the panic message I got from a serial console and below
that is a dmesg from today.
