[Xen-users] domU network falling asleep

Hi there,

One of my dom0's has taken to tcp sleeping, where an ssh session will just freeze up, as though paused. "Nudging" the stack with tcpdump (or other network activity) on another terminal wakes up the the first terminal. Then it's all back to normal, for a varying amount of time (4-30 minutes) til the console goes to sleep again, and it "freezes". Happens to all the open consoles at once, except for the one accessed via "xm console <domU>".

Any pointers as to where I should start digging?

Many Thanks!
