NFS client bugs under 2.1.48?

The NFS client code appears to be buggy under 2.1.48. I've
experienced the following symptoms:

* RCS won't check in or check out files on an NFS mounted filesystem.
This appears to be fairly repeatable. I didn't have the time to
track down why.

* This one isn't guaranteed repeatable (race?)
I was editing a perl script with emacs on one machine, the file
system on which the script lives being NFS mounted from the server.
I was running the script on the server. I made some changes to the
script, and saved. I ran the script, and noticed that the changes
hadn't got through to the server. Aha, I thought, NFS write
buffering or something. So, I did 'sync' and waited a bit. The
changes still didn't get through. So, I made another change to the
file and saved again. This time, the file got completely munged;
the first few pages of the script were gone. I saved the file from
the editor to local disk, rebooted in 2.0.xx, and copied it back
across to the server.

This has happened a couple of times, but not predictably.

Sorry for the lack of detail and repeatability here, but I haven't yet
had time to probe further. Do these soudn like known problems, or are
others experiencing similar things? The server is a Sun running
Solaris 2.5.1, BTW.
