I had the dom0 which unfortunately didn''t have a console on it hit a race condition and saw oom errors on it also.

hi james, the win2008r2 vm crash problem while migration seems related about the AllocatePage. according to the previous BSOD info, we modified code to test if page address after AllocatePage is FFFFFA8000000000 or FFFFFA8000000002. if FFFFFA8000000000 , then free it immediately, and allocate again. the test result shows 12948535073500: XenPCI --- AllocatePages IRQL = 0, Buf =

Hi, One of my servers has had its dom0 "oops" over and over twice in the last week. Unfortunately this is newly deployed so I have no idea if it is down to Xen or not. xen_changeset : Mon Dec 12 18:47:47 2005 +0100 8270:4ad23e798798 dom0 kernel is a vanilla 2.6.12 with Ralph''s .6+xen kernel patch applied. x86_32 sarge packages were used.

Hello, I''m running into some trouble with what appear on the surface to be OOM issues in Dom0, but I''m not seeing any other evidence. This typically happens during periods of high I/O, and has occurred during RAID initial sync, and mkfs.ext4ing (as a test, no intention to keep ext4 on this array). I''ve found some older posts citing very similar circumstances, however

I am having the exact same problems with my linux box. I have a 486, 24Mb of ram, and a RAID 1 partition. The box runs dhcp, xinetd, telnetd, and samba. It currently only serves the RAID 1 partition via samba to a single Win98 box. Under any large file transfer to the linux box, regardless of which machine initiates the x-fer, the linux box kernel panics and dies. Currently, I have tried

Hello, I've just run out of memory on a dual xeon with 5GB ram, considering there should have been around 4GB free (not counting buffers and cache)... this is unusual. Now after it OOM'ed I tried running top and memory usage was fine (around 1GB of 5, no swap usage of 12GB). So I thought it was a temporary thing, but processes kept on OOM'ing for no understandable reason... while

Hi all. Every few days I am getting a message that looks like the one I have cut and pasted below. It is accompanied by a severe slowdown of the system. In fact, it's practically locked. The machine runs gnome-desktops for 40 users plus about a hundred sessions of a curses based point of sale software, plus a few other functions, so it's a busy machine. Dual Xeon 3.2GHz processors.
