Thanks for all the replies. I performed a smartctl -a test and it looks
ok, despite /dev/sda is 59°C pretty close to the Drive Trip Temperature
60 °C.<br>
hdparm results:<br>
<br>
Device: HP 18.2GB A 80-S1A0 Version: S1A0<br>
/dev/sda: <br>
Timing buffer-cache reads: 428 MB in 2.00 seconds = 214.00 MB/sec<br>
Timing buffered disk reads: 78 MB in 3.00 seconds = 26.00 MB/sec<br>
Device: COMPAQ BD0186349B Version: 3B05 <br>
/dev/sdb:<br>
Timing buffer-cache reads: 428 MB in 2.00 seconds = 214.00 MB/sec<br>
Timing buffered disk reads: 66 MB in 3.07 seconds = 21.50 MB/sec<br>

Looks pretty the same to me. <br>
I am somehow thinking of a memory related problem, but I have some
questions. The previous install was on a pentium III 866Mhz 768Mb PC100
ram 2x 10Gb ATA66 Disks RAID1, and it crashed every 20 days more or
less (it happened also 2 times in 2 days). This install is on a Celeron
1300Mhz, 512 Mb PC133 Ram Computer, 2x 18Gb SCSI RAID1, and it has
crashed after 30 days. Power supply is different as well as the entire
case/motherboard and whatever you can imagine (know it is not really
server hardware, but it's what they gave me, and I won't give up on
having Linux present in the company). It's 2 completely different
machines, but the issue is the same, so maybe I'm wrong, but I would
exclude the power supply or disks or mobo. <br>
I thought of the memory like Brian suggested, considering that under a
high load it could heavily swap leading to the panic, even though top
doesn't show such a heavy memory usage or swapping during normal
operation. <br>
<br>
Is there a way to get more info on the machine state just previous to
the panic? <br>
<br>
Thanks for all your help<br>

<pre wrap="">Hi list,
I periodically experience kernel panics on my wbel3 box. This server is
running as a front end mail filter for exchange, with a typical
MailScanner - sendmail - clamav setup. I also have mailwatch for
mailscanner running, which is a LAMP kind setup. Every 3-4 weeks I have
a crash, with keyboard blinking lights, and I don't understand the
reason for it. Recently installed a new server same configuration, 2 x
18Gb scsi disks raid1, thinking it was possibly a hardware problem, but
this morning after a month running fine, I had the first crash. Could
you please tell me where to look for possible indications on what could
have caused the panic? Checked log/messages but it looks like no useful
info is in there.

We faced a similar behaviour on server running RH9. Two changes were
done and till date I do not know for certain if any were responsible.
1. Upgraded the power supply with higher wattage.
2. Changed the drive cables as on of the drives was giving slow results
when checked with #hdparm -tT /dev/sd[ac]
