Description of problem:
The system is a DELL Poweredge 2550 rackmount PIII server, currently very
lightly loaded (not yet in service). The kernel did an 'oops' in the early
morning (04:04 local time, GMT +12). Would respond to pings, but attempts to
connect with ftp, ssh or to login to the console all just hang. I rebooted it
and checked in /var/log/messages where I found the 'oops' message.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Rebooted the sytem today, wait to see if it happens again.
We use the same version of RedHat (7.3, kernel 2.4.18-10 i686) on several
servers here (Not the same hardware though) and have had no problems like this.
The system is being used by two developers who are using MySQL and PHP/apache
and were not using it at the time of the incident. The system is also being used
as an anonymous ftp server for kickstart installs to a small lab and as a
printserver. None of these generate much load.
IPchains config denies access from all but a few local addresses. Kernel is
stock 2.4.18-10 from the binary RPM, verifies ok.
Not much info in the /var/log/messages file, just:

Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem
The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases,
and if you believe this bug is interesting to them, please report the problem in
the bug tracker at: http://bugzilla.fedora.us/
