Lots of possibilities, though I am not sure you have supplied enough
information to hazard a guess (unless someone ran into this before and
already knows the answer).

An operation on an NFS mounted file system can hang when:

1) the nfs server becomes unresponsive (crash, overload, file system
full, ...)
2) the client becomes unresponsive ...
3) the network becomes unresponsive ...

If you could indicate more details, it is likely someone might be able
to tell you where to look next.
