Hello,
I thought this was a library issue per workstation for quite awhile.
However, I have narrowed it down to this problem.
I can run programs such as nautilus, staroffice, openoffice as a local
user just fine. However, if I try to run any of the above programs as a
nis user who's home directory is an nfs mount, that program will hang.
for example (staroffice):
todd@ws04~ $ strace -f /usr/local/office/program/soffice
[snip]
[pid 589] open("/home/t/todd/.sversionrc", O_RDONLY) = 3
[pid 589] fcntl(3, F_GETFD) = 0
[pid 589] fcntl(3, F_SETFD, FD_CLOEXEC) = 0
[pid 589] fcntl(3, F_SETLKW, {type=F_RDLCK, whence=SEEK_SET, start=0, len=0}
This of course all occurred as soon as I upgraded debian stable to the
latest packages.
I am not sure how to track this problem any further.
I will add that as a local user there is no problem whatsoever.
but as a nis/nfs user some programs fail with similar results.
mozilla works fine, and obviously that is setup with a local binary, and
the configuration is read over nfs.
Could somebody please help me debug this further, or better yet tell me
what I need do to fix this problem.
I can easily provide more information, if somebody can tell me what would
be pertinent.
I am not a subscriber to the nfs mailing list (yet) so please reply to me
as well as the list please.
Thanks all!

I've seen software hang doing a fcntl(F_SETLKW) on an NFS-mounted file when lockd
was not running or was firewalled off. Essentially the client is asking for a
lock on a file -- which it never gets -- and the app waits forever for lockd to
respond.
I would check that lockd is running on the client and server, with rpcinfo -p,
and that it is not firewalled off.

Much appreciate the help!

I'm looking into how to get lockd running. (or can you help with that
too?)

Here is the output of rpcinfo -p on the Workstation and the Server

I would add that all these programs worked fine before I did an apt-get
update ; apt-get dist-upgrade which upgraded about 35 packages (so I am
not sure what caused the problem).

You can try from your client to see if it can talk to the lockd on the
server. This should give you some positive response:
rpcinfo -u <servername> nlockmgr
and likewise you can run this from the server as well.
Also keep in mind what you did to your systems is prone to breakage of all
sorts; arbitrarily upgrading ~35 packages on your system, when you don't
even know what all of those packages are, much less the effect of an
upgrade, you pretty much expect some things to stop working properly. It's
off the scope of this list to go through all the packages you upgraded,
though.
