Is anyone else having problem with Xen Crashes or can provide hints why this happens? I can resolve it by restarting /etc/init.d/xendomains but I'm curios why it happens, the machine is running 64bit Centos 5, 16GB memory. I have some other programs reporting exhausted shared memory so maybe thats a cause?

kernel: xenbr0: port 4(tap1) entering disabled state
