Re: [Xen-users] intermittent network hangs

On a 2.0.6 installation on top of Debian and kernel 2.6.11.12 (Dell PE1750, tg3
nic), I'm seeing temporary network hangs while working on the child domains.
From
outside the install, pinging domain0 results in 0% packet loss while pinging any
of its child domains results in roughly 1% packet loss over a multi-hour ping.
While ssh'd in, a hang appears to occur every ~10 minutes and lasts for 3-7
seconds.
I've seen this pattern on hosts with errors in the bridge config.
Especially when more than one bridge was used.
The default spanning tree ageing time is set to 300 secs. That's more
than your ~10 minutes, though.
'brctl showstp xen-br0' and
'brctl showmacs xen-br0'
Connectivity to domain0 is never interrupted and no external packet loss occurs.
I'm also not seeing any interruption between the child and domain0.
I see no kernel messages, nothing in the logs, etc. Any ideas on what's going
on?
