[comp.sys.mac.system] Strange file problem

I know it is not halloween, but here is a scary problem. At least, it
made me shudder and gave me a headache.

We are having occasional occurrences of file contents being replaced
by the contents of other unrelated files on our Appleshare server. Not
corrupted files, but nice pristine files, that just happen to be other
files than the ones they are supposed to be.

Example: Two artists working on graphics. One called "Man Slain." One
called "Where the body was found' (we're a newspaper. we do gory stuff
like that).

Borth artists store their graphics. One goes back to work on "Man
Slain" a little later and finds the contents have been replaced with
the contents of "Where the body was found"

There was no operator error. These are two of the most competent Mac
users in the company, and this is something that has happened on other
occasions to other users. It has also happened with more than one
application and on more than one or two Macs. The server seems to be
the only common element.

What could be causing this?

Our server is a Mac IIcx with a Daystar 40mhz accellerator. It is
running System 6.0.5, Appleshare 2.0.1 and Quickmail Server 2.2. It
has two 600mb Imprimis drives, formatted with Silverlining 5.28 using
Macintosh Hardware Handshake read/write loops. Each drive is divided
into several partitions (also with Silverlining).

I could make a wild exptrapolation and say that the problems started
about the time I installed new drivers with Silver Lining, but that
would be a very wild guess. I have no hard evidence connecting the
beginning of these problems to any specific occurrence on the server.

Please respond. I'm stumped. tonight I'm going to reinstall all
network system and server software and do some complete tests on the
drives, but that's just my "don't know what else to do" solution. If
anyone has specific info on it, I would be ecstatic.
