Good day,

We're using the FC6-branch of 3.0.3 on some of our machines. On nodes with broadcom-based network interfaces this works just fine, but on those with intel e1000-based interface cards, about once a week I'm seeing a lot of this:

Nov 30 19:02:02 yankee kernel: printk: 4 messages suppressed.
Nov 30 19:02:02 yankee kernel: xen_net: Memory squeeze in netback driver.
Nov 30 19:02:07 yankee kernel: printk: 4 messages suppressed.
Nov 30 19:02:07 yankee kernel: xen_net: Memory squeeze in netback driver.
Nov 30 19:02:12 yankee kernel: printk: 4 messages suppressed.

All vifs become unreachable, until I stop or restart one guest, then everything comes back to normal. Is this a known problem?

Cheers,
Pim
