I've been running into this from time to time... usually when xm creating a new domU, /var/log/messages for dom0 spits out:

<snip>
May  3 02:56:04 tweak kernel: printk: 4 messages suppressed.
May  3 02:56:04 tweak kernel: xen_net: Memory squeeze in netback driver.
</snip>

And at this point all of the network connectivity for *all* domU's controlled for that dom0 vanish. I have to xm shutdown and xm create them again to get the network back. This doesn't happen all of the time, seems rather random really.

Its *really* annoying.  Is there a way to prevent this from happening?
