I got this too (by starting too much torrents at once=85)

My understanding is that FreeBSD is not really dynamic concerning
memory allocations for the network, so I bumped up the limits in
/boot/loader.conf:

kern.ipc.nmbclusters=3D"51200"
kern.ipc.nmbjumbop=3D"51200"

netstat -m is really useful to see what's going on.

My dom0 is Linux 3.2, but I don't think that this problem is specific to
Xen in any way.

Best
