[Xen-devel] More on networking hang

[Rob Gardner <rob.gardner@xxxxxx>]

I saw something go by on the list a week or so ago about network hangs, 
and I may be observing something similar.
The basic setup is: two guest domains running apache, and a different 
box running httpperf against them, 100 requests per second for the same 
100kbyte file.
This runs ok for a time, then suddenly chokes and all traffic comes to a 
stop. Then a few seconds later traffic seems to pick up again.
This behavior is not observed with a workload of 40 requests/second. At 
80/second, the problem starts appearing, but not very frequently.
We can provide sufficient detail if anyone wants to try to reproduce this.

Have there been any fixes relating to this lately? We are using xen bits 
that are a few weeks old right now.
