As you might guess, this rpcinfo output indicates nfsd wasn't running. I
am seeing this:

can't bind udp addr *: Address already in use

in syslog. Setting this:

nfs_server_flags="-t -n 4"

allowed it to startup, but it then timed out an fsinfo call. Adding -o
to the nfs_server_flags to use the old nfs server allowed vmware to
mount. FWIW, I can't find any reason for the udp message above, nothing
seems to be using it that I can find. Ideas? tcpdumps are available if
anyone want them.
