Is this indicative of a hardware problem? I recently had memory issues with another machine - I did run memtest86+ after this crash though not for very long (no errors.) I had no problems compiling ksymoops though. I've also recently been having problems getting rpc.nfsd to run, though I couldn't say if it's related. I ran it through strace and although I don't know what I'm looking for there were a few odd things that stood out. Basically nfsd couldn't contact the localhost, which is strange, because it only stopped working recently, and I have nothing blocking it (firewalls, etc.) Thanks again, -- Matt. --1LKvkjL3sHcu1TtY Content-Type: message/rfc822 Content-Disposition: inline Date: Thu, 22 Jul 2004 19:50:10 -0400 From: Matt DeLuco To: linux-kernel@vger.kernel.org Subject: oops related crash Message-ID: <20040722235010.GA2483@mobius.su.shawcable.net> Mime-Version: 1.0 Content-Type: multipart/mixed; boundary="gKMricLos+KVdGMg" Content-Disposition: inline X-URL: http://spacebox.net/ X-HTML: HTML in email is a Bad Thing(tm). User-Agent: Mutt/1.5.6i --gKMricLos+KVdGMg Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Hi, last night I had a seemingly random crash with serveral oopses. I say random because my debug log showed nothing for 7 hours between the last log and the oops log. Though I don't really know if that's significant. Anywho, I read Documentation/oops-tracing.txt. As suggested I ran the oops through ksymoops and I've attached the output. I'm not sure how reliable it'll be.. I had to edit all the log stuff (host, date/time, etc.) out of the oops. I'm running a "vanilla" 2.4.26 kernel with a patch I inserted manually to prevent distcc from causing the system to crash. The patch seemed to be holding up well, and nothing was being compiled at the time of last night's oops attack. I have attached the patch (which I found on the lkml.) Sorry for not having done much else, but my skills in dealing with the kernel are.. limited at best. I hope this info is useful. Please let me know if there's anything else I can do.
