Hi,
I'm experiencing the following issue:
Our UML's seem to hang consistently 2 times per minute for 2-10 seconds. I can
type at SSH but it takes a few seconds for it to appear. 'ping' stops too, but
does catch up (this is pinging from the host server to the virtual server):

64 bytes from test2.vserv (192.168.x.z): icmp_seq=52 ttl=64 time=0.088 ms
Just to be clear: SSH on the host server itself does not hang like this.
It's not just the (virtual) network, the direct terminal (a tty of the ./linux
process in a 'screen') hangs as well.
I've tried running 'top' on the VM, but it doesn't reveal anything (no process
>10% CPU). At the moment it stalls, 'top' stalls as well, so doesn't help
much. 'top' on the host doesn't show anything CPU heavy either (no process
more than a few % CPU, actually)
Do you guys have any idea? Is this a known issue? Where to look?
Both the UML and the host are running kernel 2.6.32.
Thanks in advance,
Bram Matthys.
