recently as in it used to work better?

what options are you using to mount other then soft/hard?

my options:

nfsvers=3,rsize=8192,wsize=8192,rw

it may be a locking issue, at least on my debian linux(2.2.19) nfs
server it's really bad at locking, fairly sure it's a debian issue
as rpc.lockd is what fails(/etc/init.d/nfs-common restart always fixes
it), rather then a kernel issue. my redhat 7.3 nfs server(2.4.18) works
better with locking.

GNOME apps are especially locking intensive, many of them may stall
if nfs locking is broken.
