RE: NFS problems between RHEL4 U3 and RHEL4U6

No. In the case where saving the file takes minutes, there is an fstab
entry:
server:/home           /home                   nfs     rw,sync,bg
In the other one, I have it set up for automounting:
Auto.master
/mnts   /etc/auto.mnts          --timeout=60
Auto.mnts:
*          -fstype=nfs,rw,nosuid,soft     server:/mnts/&

The fstab and auto.* entries are identical on all of our systems. 

The one differences is on the one client system that is running RHEL4U3,
writing to /home in our test is very fast (about 1 second) where writing
to /home/<user> on the RHEL4U6 servers takes minutes. But, writing to
/mnts/buildarea/<user> is also takes about 1 second. On difference is
the options. I can try a few things.
