These affect the operation of NFSv3 writes so it is just possible that they would affect you. It appears that you have tried both v2 and v3 so this is a long shot. Can you break into the machine with DDB? Can you get a packet trace using "tcpdump -vv -s 500" (record the trace on a machine which is not going to crash in the test :-). If you are testing NFSv3, make sure it is a recent version (the NFSv3 changes seem to be there in the 2.2 branch). -- Doug Rabson, Microsoft RenderMorphics Ltd.
