I suspect this has less to do with actual memory and more to do with some
other buffer-like bottleneck.  Does tuning any of the network buffers make
any difference?  A couple to try:

net.inet.ip.intr_queue_maxlen
net.link.ifqmaxlen
kern.ipc.nmbclusters

If possible, does changing from VM bridged -> NAT or vice-versa result in
any behavior change?


Also check vmstat -z, net.graph.maxdata may be a candidate as well.

I tried FTP (to have something completely different) and it fails as well:
(ftp: netout: Cannot allocate memory)

I watched vmstat -z, and every time it fails, I have another failure reported for "NetGraph data items".
