Subject: Oops in kjournald
Date: Tue, 11 Jan 2005 10:05:46 +0100	[thread overview]
Message-ID: <20050111090546.GB25756@sys-241.netcologne.de> (raw)

In the last week I got the following Oops five times on two machines,
when they are under very heavy load  (mailserver based on Debian sarge
with postfix 2.1.4) when the load is >4 for some hours.

I run a 2.6.10 kernel (with aacraid 1.1.5 2372 driver from Adaptec,
everything else vanilla) on Dual Xeon machines. The kernel has ext3fs
and XFS compiled in but currently all filesystems are ext3.

In the logs I don't see anything, because the machines freeze with the
above message (I retyped the messages from the screen, so there may be
some typos, if necessary I have a screenshot here to correct some
misspellings).

What can I do to fix this problem?  Using google I didn't find a hint
for further search, but my kernel knowledge is very limited :-|

Tschoeeee
