[comp.soft-sys.andrew] "old hidden messages"

oester+@rchland.ibm.com (Bob Oesterlin) (11/01/90)

Well, it happened again. This time  I did a little poking around in
themessage folder. In this case, I just posted 2 messages to
"advisor.aix31".Messages exposed the folder, but there were no new
messages:

What's curious is that 2 new messages appear that were not present in
the dirpreviously!

What's going on here??

PS: The bboard machine is an RT running 4.3, AFS 3. The configuration
has beenstable for at least 6 months.

Very curious.  Is the total number of files the same?  That is, are the
two new files just renamed old ones, or did they really appear out of
nowhere?

This is a very unfamiliar bug.  I'll keep thinking about it.
