Hi Boys (any girl here :P)

System was running ok until today. I had to reboot server manually.
This is the first one Oops since a  long time ago (last was on xfs  1.0.2)
This server is not using NFS server.
We use some perl script, java tools for internal worflow system.

I am checking if one of them used too much resources, but it looks like it
was random.

HW: PE6450
Mem: 2GB
Swap: 2104432K (around 2GB)
CPU: 4 PIII 700Mhz
RAID Card: Perc2 with MegaRAID chip. (Vendor: MegaRAID Model: LD0 RAID1
8232R Rev: 161J)
OS: RH 7.2 (Obvious, plus XFS 1.1)

I will check if I need update firmware.

If you have experienced similar Oops (Paul Petersen??)
Please give me your comments about how did you fix it.


Thanks

Vene
