Still, it looks like mountd might be misbehaving. That is a good place to start anyway. Can you strace mountd while you attempt a mount? e.g. strace -o /tmp/trace -s 1000 -p 241 and send the /tmp/trace. Also, after the attempt fails, run rpcdebug -m rpc -s cache grep . /proc/net/rpc/*/c* cat /proc/fs/nfsd/exports and report the output.
