We're trying to use FAM to monitor files on a directory that is mounted via NFS.

This works fine when a file is modified via the local machine on which FAM is
running.  When the file is changed from the server that is exporting NFS,
however, FAM does not detect this, and does nothing.

I have tried this two ways: At first, we had a FAM server running on the NFS server (as well as on our client). When that didn't work, we disabled the FAM server on the NFS server, so that only the client has a FAM server running. As
I understand it, it should do polling in this case.

I've checked all the config files & options and everything seems to be OK.
We're invoking FAM with "/usr/bin/fam -t 6 -T 0".  The -t 6 should be the
default, but I tried it anyway. I've tried it with -C, and that doesn't make any difference. I also ran with the "-d" option to see debugging messages, and
nothing is generated when the file is changed remotely.

Both client and server are RedHat 8.0 machines.  Does anyone know what the
problem could be, or can offer any suggestions?  Thanks.
