You would get much more traction if you CC-ed me.
Anyhow, no idea - 2.6.32-41 is a bit ancient and this thread does not
seem to have relevant data (such as serial console for examples, or the
"some crashes").

Thanks.  I have now setup serial console too
Adding more infos:  it happened in the night when there are some heavy rsync from guests to a nfs server for backup purpose.

Just thinking about this one:

Page allocation failure with e1000
http://lists.debian.org/debian-backports/2011/01/msg00037.html
http://forums.gentoo.org/viewtopic-t-899896.html

and this one:
http://xen.1045712.n5.nabble.com/devel-next-2-6-39-SLUB-Unable-to-allocate-memory-on-node-1-gfp-0x20-tt4418288.html#a4422100


Maybe something related to e1000e driver?
Increasing /proc/sys/vm/min_free_kbytes can help? 


xend-config.sxp relevant entries
(dom0-min-mem 1024)
(enable-dom0-ballooning no)

grub relevant entry
kernel          /boot/xen-4.0.1.gz dom0_mem=1024M max_cstate=1

Do I need to add  'mem=1GB'  too?
Thanks
