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.
