From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.1) Gecko/20020827 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): kernel-2.4.18-10 How reproducible: Didn't try Steps to Reproduce: 1.Rebooted the sytem today, wait to see if it happens again. 2. 3. Additional info: 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: Sep 9 04:04:51 belo kernel: Unable to handle kernel NULL pointer dereference at virtual address 00000000 Sep 9 04:04:51 belo kernel: printing eip: Sep 9 04:04:51 belo kernel: c014316f Sep 9 04:04:51 belo kernel: *pde = 00000000 Sep 9 04:04:51 belo kernel: Oops: 0000
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 persists. 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/
