My company is running a TOPS network of Mac II's (4.1/5.5) over Phonenet
cabling.  Machines which have published folders will intermittently
crash with bus errors when someone else on the network tries to copy a 
file from them.  The crash generally happens after the file has been copied.
The problem has no clear correlation with what the server is doing (it's
even happened in the Finder's idle loop).  The problem never occurs 
when we try to duplicate it :-)

The only INIT we use that didn't come from Apple or TOPS is TMON Startup,
but a machine without TMON has crashed with the same symptoms.

The TOPS folks suggested a software upgrade (which hasn't completely
solved things).  Beyond that they say they can't duplicate the problem.
I believe them.  I'm running on the assumption that something in our
configuration is destabilizing TOPS.

Has anyone seen this failure mode before?  If so, were you able to fix it?
If so, could you please (please!  beg, beg, beg) explain how?

If email doesn't get through I can take phone calls at (206)462-0501.
