It appears that the above isn't the case. I managed to get a failure of
nfs in UDP mode as well. I got some messages about jumbo frames that
didn't make sense coming from the NIC when that happened and some
corruption of files. I believe there is an issue with mpsafe on the sk0
Turning off debug.mpsafenet (i.e. setting to 0) seems to have resolved
the issue for me at the moment.
