  • Thread-topic: network hang trigger

I have found that simply doing a ping with packetsize > 1500 (maybe
mtu???) causes the network to hang for a short time. This is from xenU
and xen0 on the same machine.

Can someone else _please_ test this? I am able to make the network hang
by saying from domU:
ping -s 1473 <dom0 ip>
(1473 + 28 byte header = 1501 byte packet)

I'll do more testing tomorrow.
