I'm with Charles on this

I had a scenario a few years ago where we kept loosing the BP file

turned out that we had an active select wish a record key of BP in it and a 
basic delete was isssued and that cleared out the file (yes i know it doesnt 
sound right but i happenend)

I bet its a condition such as that and not malicious at all

My first guess would be a TCL DELETE command  that was expecting a hightly 
restrictive select list active,  but instead had the whole file.   Or instead 
of TCL delete,  it could be a basic program that did the same inside a readnext 
loop.
 
Or what about an SQL DELETE?    I think the defualt there clears a file, i.e., 
there is no WHERE clause. 
 
 
One way the TCL DELETE  (or loop-readnext) scenario could happen would be if 
there were a 2-stage select,  and the second did NOT use REQUIRE.SELECT (aka 
SELECT.ONLY ) keyword.
 
A simple example:
 
   SELECT MASTERf WITH AGE > TWO.YEARS SAVING LINEITEM.IDS
   SELECT LINEITEM    ( <----   you _n_e_e_d_ REQUIRE.SELECT here !!!! )
   DELETE LINEITEM
 
Suppose the 1st select comes up blank.
Then the second will be a select list of all LINEITEM ids.
Then the DELETE effectively clears the LINEITEM file.
 
That's where I would look first.

... an incident last week were one of more heavily used files, the LINEITEM 
file, all of the sudden  go to 0 bytes. Normally, this file has over 46K 
records.  It wasn't a peak load time, and there haven't been any recent changes 
to any BP's.
We had it happen again on another system, to the same file, LINEITEM. 2 
Different boxes, 2 different files (same name) @ 2 different times....
