I have a multi-user application that executes on a runtime on a file server.  
I didn’t split the database by “front-end” (forms) and “back end” (data).  
When there is no corruption, the database runs smoothly for days. On
occasions, the database gets corrupted thereby needing a manual “compact and
repair” process.  

The Error Message is:
"The database “\\Land\Copy (3) of Property.mdb“ needs to be repaired or
isn’t a database file. You or another user may have unexpectedly quit
Microsoft Office Access while a Microsoft Office Access database was open. Do
you want Microsoft Office Access to attempt to repair the database?"

I created a program, within the database, to monitor users’ login and
logout.  This captures all users’ activities including “abnormal exits” (date
and time).  There doesn’t seem to be any pattern of users exiting abnormally
that would cause the corruptions.  The database (“mdb”) gets corrupted even
when there are no abnormal user exits.

What could possibly cause the corruption?
