Hello,
Summary: Guests suddenly loosing Network-Interfaces.
Description:
we've noticed a problem on 2 of our hosts, not sure if this could be related to linux-vserver.
The System hosting between 5-15 Linux-Vserver running with kernel 2.6.26-2-vserver-amd64.
Both Systems suddenly through out this error (kernel.log):

And some of the Guests lost their network-interface. After a restart of the guest the network interface comes back online, but this problem occurred several times.
