Hi Ron, Thanks for your advice. Nothing has changed for several weeks in the code base and nothing recently regarding arrays.
We regularly check and repair with MSC if necessarily and always rebuild indexes when we do. I’m suspecting some i/o problems, perhaps with a volume mounted in SMB. Also, we have just started having a few users with OS X 10.3.
