Hi,

Did you find a solution?

I have the same problem when transfering large files too, I am testing 
with selinux off and it seems so far not to crash.
My dom0 and domU are all CentOs 5 which runs Xen 3.03 from the distro.

Also, I use aoe and I changed the defaulf network interface used by the 
aoe instantiator from
aoe-stat      e9.0        10.737GB xenbr0,eth1,eth0 up
to
aoe-stat      e9.0        10.737GB   eth1 up

So far it seems to have fixed the crashes.

What have you done to fix the issue ?

Regards,
