Works great over NFS; I've used it this way for years now.  There should
be messages in syslog or on the console that might provide a clue.

(But lately I've had reasonably good luck by starting _any_
troubleshooting for odd problems like this by looking at selinux first,
or better yet just turn selinux off and see if whatever strange issue
you have doesn't just go away.)
