How can I test it? What kernel version are you running? I can assure you that some versions are _rock_solid_! My best uptime so far has been 419 days (unfortunately a hardware upgrade forced me to shutdown...) However I must admit that I don't have to much experience with SMP under Linux. If you want to test your memory, you might want to check memtest86 (assuming you're using Linux on an Intel-compatible system, of course): http://reality.sgi.com/cbrady_denver/memtest86/ ---------------------------------- Alain Borel Year 2000: not the 21st century Date: 04-Jul-00 Time: 17:37:55 From chemistry-request@server.ccl.net Tue Jul 4 11:59:34 2000 Received: from yogi.pc1.uni-duesseldorf.de (yogi.pc1.uni-duesseldorf.de [134.99.152.44]) by server.ccl.net (8.8.7/8.8.7) with ESMTP id LAA25652 for ; Tue, 4 Jul 2000 11:59:33 -0400 Received: (from jochen@localhost) by yogi.pc1.uni-duesseldorf.de (8.9.3/8.9.3) id SAA03478; Tue, 4 Jul 2000 18:00:04 +0200 MIME-Version: 1.0 Content-Type: text/plain; charset=iso-8859-1 Message-ID: <14690.2563.245509.868855@yogi.pc1.uni-duesseldorf.de> Date: Tue, 4 Jul 2000 18:00:03 +0200 (CEST) From: Jochen Kuepper To: Krzysztof Radacki Cc: chemistry@ccl.net Subject: CCL:Problem with stability of linux In-Reply-To: <001501bfe511$5c3bf060$d43b8286@dorf.rwthaachen.de> References: <001501bfe511$5c3bf060$d43b8286@dorf.rwthaachen.de> X-Mailer: VM 6.72 under 21.1 (patch 9) "Canyonlands" XEmacs Lucid Content-Transfer-Encoding: 8bit X-MIME-Autoconverted: from quoted-printable to 8bit by server.ccl.net id LAA25653 Krzysztof Radacki writes: > I got some problems with the linux-box on which I work. > Real often the maschine hang during gaussian calculations > in SMP-modus with following message (just example): > ==== > Unable to handle kernel NULL pointer dereference at virtual adress > 00000018 > current -> tss.cr3 = 0e0a6000, %cr3 = 0e0a6000 > *pde = 00000000 > Oops = 0000 > CPU = 1 > EIP = 0010: [] > EFLAGS: 00010207 > ax: a7553000 ebx: daad4000 ecx: 00000000 edx: c023c000 > esi: 00000000 edi: 00000000 edp: daad5fbe esp: daad5f9c > de: 0018 ec: 0018 sw: 0019 > Process l502.exe (pid:727, process nr:7, stackpage: daad5f9c > Stack: 00000000....... some lines > CallTrace : [] > Code: 8b 41 18 c1 f8 d1 03 41 1c 89 41 18 > 8b 49 34 81 f9 00 c0 23 > ====== > The questions: why and what should I do again :) > Is it problem of software (I've change the kernel and I can't see any = > difference), > is it SMP-hardware or maybe memory? How can I test it? Looks like a kernel problem (due to hardware failure or not). Do some oops-tracing (look in your kernel sources for documentation) and ask on linux mls or newsgroups.
