[Xen-users] Memory squeeze in netback driver?

[Jason Dillon <jason@xxxxxxxxxxxx>]

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?
