Here''s the log... I''m running 1 VM in Linux domain.... I have
been
running specjbb (cpu, memory intensive)... since it appears 3
applications are causing it to malfunction, I''m going to update to the
latest python, stop kjournald, and if that doesn''t work try updating
X... (I also use VMX domains which cause similar issues, although I
don''t have a log to prove it). If this is a known problem... or
something else... please let me know.
Thanks,
David

> Here''s the log... I''m running 1 VM in Linux domain....Do you mean dom0 plus 1 other domain? CONFIG_SMP got enabled by default recently, but I''d be slightly surprised if that was the problem as a bunch of people had tested it pretty hard. Similarly for CONFIG_HIGHMEM4G. It would be great if you could try and get a simple recipe to reproduce.

Yeah, I''m trying to piece together if this is a bug in the image (from possible corruption ... Repeated crashes)... Or if it''s a xen / kernel issue. I just created a new VMX domain and ran specjbb on it for appr 1240 minutes... It was only running for 40 mins or less on a Linux domain (and yes I do mean dom0 + 1 VM / domU)... I''m going to copy my image for the VMX domain to a Linux domain and see if the issue reappears... If it doesn''t, I''ll chalk it up to silliness... Otherwise, I''ll continue to research. I have disabled CONFIG_SMP on both xenU and xen0 I have disabled CONFIG_HIGHMEM4G on xen0 I have enabled CONFIG_HIGHMEM4G on xenU I can send you the rest of my .config(s) if you''re interested. Regarding the objdump, what exactly am I looking to do here... I''m not familiar with low level kernel hacking.

Problem didn''t go away... So here''s some more details... OS: FC3 (dom0 and domU) Xen: updated Saturday via mercurial around 4 PM CST (5 PM EST / NY time) Dom0 config... X11, Gnome, ext3 disk, disabled HIMEM and SMP DomU config... Specjbb2000, BEA JRE 5r7 (latest release), disabled SMP, enabled HIMEM Processor is running with VT enabled and disabled Hyperthreading disabled Linux Kernel: 2.6.11.12 This is not an issue with my linux install or my image, as I am able to run a VMX domain flawlessly with the same configuration as my Linux domain. The only thing of significance from my domain config is the ram, which is set to 1664 (MB) I have run mrproper and clean on my xen several times. Well it hasn''t crashed in the past 60 mins, I have received this message "Bad rx buffer (memory squeeze?)" I''ll update as more comes in.

Sorry for the spam, FYI, I am running specjbb with a heap size of 1500 and with 1 thread for 10 minutes. It stops than restarts. It would appear to be a memory reallocation issue. Thanks, David -----Original Message----- From: Ian Pratt [mailto:m+Ian.Pratt@cl.cam.ac.uk] Sent: Sunday, July 10, 2005 12:47 PM To: Wolinsky, David; xen-devel@lists.xensource.com Cc: ian.pratt@cl.cam.ac.uk Subject: RE: [Xen-devel] Lot''s of OOPS> Here''s the log... I''m running 1 VM in Linux domain....Do you mean dom0 plus 1 other domain? CONFIG_SMP got enabled by default recently, but I''d be slightly surprised if that was the problem as a bunch of people had tested it pretty hard. Similarly for CONFIG_HIGHMEM4G. It would be great if you could try and get a simple recipe to reproduce.

Do you mean dom0 plus 1 other domain?
CONFIG_SMP got enabled by default recently, but I''d be slightly
surprised if that was the problem as a bunch of people had tested it
pretty hard. Similarly for CONFIG_HIGHMEM4G.
It would be great if you could try and get a simple recipe to reproduce.
Thanks,
Ian

I am seeing the same problem on an x86 machine, as soon as I create a DomU (no loads running!). I first saw this last Friday, I believe. Oops: 0002 [#1] PREEMPT SMP modules linked in: CPU: 0 EIP: 0061:[<00244ec0>] Not tainted VLI I submitted Defect #96 to the Xensource Bugzilla system to track this bug.

Thanks! I was afraid I was losing my mind!!! (I spent well over 15 hours trying to figure out if it was me or xen...) An update ... The problem isn''t with my xen config either. I just downloaded the latest precompiled (binary) xen and the issue still existed. Thanks for submitting to bugzilla, I just wanted to make sure it was Xen before I did.
