[Xen-users] Xen stability

["Angel L. Mateo" <amateo@xxxxx>]

Hello,

        I am testing xen to running it in a production environment. At this
moment I am in the test state. But I am having problems with Xen. I run
it in a Dell PowerEdge 750 with two P4 processors. Although it seems to
run perfectly, I have observed that after some days of run, it crashes
the system, getting the next error messages:

        All I can do is to reboot the system.

        Any help?
