I've been unable to reproduce it so far.  Has bonding always been
present in the cases you've seen, or are multiple independent interfaces
sufficient?

In the case you reported initially, openvpn was using UDP, but the peer
was dead, so there presumably wasn't much traffic from that app.  Was
there lots of NFS-over-UDP traffic also going on?

Where was the independent report on 2.6.27?
