Xen devel - Mar 2005 - 2.6.10-xen0 crash / oom / page fault

Hi!

I''m using xen 2.0 testing-src dated 03 feb 2005. 

Dom0 is running 2.6.10-xen0 patched with patch-2.6.10-as5 (security fixes).

The dom0 kernel has now crashed twice, it stays something like 3 days up
before crashing.

Syslog messages available here:
http://nrg.joroinen.fi/xen-dom0-2.6.10-xen0-crash.txt

It seems that the machine goes OOM. Dom0 is using 128 MB of RAM, and 1024 MB
of swap.

Dom0 is running Debian sarge/testing, software raid5, lvm and xen. nothing else.
I''m running couple of mostly idle xenU''s with this box. 

Any tips how to debug this? Thanks!

Somebody else seeing this? Dom0 crashed again during the weekend.. the box
reboots when the crash/oom happens.

I was running a script from the cron which logs the mem/swap/cpu usage every
5 minutes.. Analyzing the log, I didn''t see anything special before the
crash.. swap almost totally unused etc. On the other hand, 1 GB of swap is
easily filled
in 5 minutes if the python or something else goes crazy.. 

During the latest crash there were same kind of messages in the syslog..
python causing page allocation failure etc.
