I manage a network of 100 Suns and two Pyramids.  Something strange
happened today, and it has happened before, too.

A user was working on two Suns simultaneously.  He was editing one file
on one Sun, and reading the file using LaTeX on the other.  The file
was NFS mounted on both Suns.  It physically resided on the NFS server,
a Pyramid.  One of the Suns had an out-of-date copy!  It was a minute
old.

Unmounting the filesystem on the Sun client and remounting it fixed the
problem.

This is disturbing.  I would like to know what causes this.  If I have
to live with it, I would like to know what workarounds exist other than
remounting.  Of course, users cannot do this, and I am not always
around to do it for them.

Thank you.
