I spoke too soon. Now an nfs client is having problems. I ran iperf
and saw what looks like a decent rx connection, but a tx connection
where up to 2% of UDP packets are dropped (see
http://pastebin.com/m1c067417 ). If both sides are gigabit connections,
I see more like 13%. If I flip client and server sides, the results
still show issues with vge tx.
I ran iperf like this: iperf -s -u -r and iperf -c 10.0.x.x -u -r.
Other machines have problems with the vge interface, but drop no more
than a packet between themselves.
This doesn't happen with my vr interface. I gave it an IP in a
192.168.x.x subnet and repeated the test. Most of the time, zero
packets were dropped. When packets were dropped, it was fewer than 2%.
Are there any known bugs that cause UDP tx packet drops on vge?
