Corrupted DB Cross Reference File - QADBFDEP

Something strange is going on....

We were running a query over the system "Cross reference dependency file"
(QADBFDEP) and discovered that there was several inconsistencies.

For example, there were records that listed the "based on physical file" as
the library name of one of the "dependent files". The file wasn't "damaged"
in the traditional sense, it just contains obviously incorrect data.

I know how to use the RCLSTG command to rebuild this reference file, but
even after discussing this incident with IBM SupportLine, I'm unable to
determine what possible series of events could have led to this file being
corrupted. And needless to say, having to run a RCLSTG command in a system
that is as close to 7/24 as possible, presents a major scheduling problem.

Has anyone else run into problems like this with the system DB cross
reference files? I've been a Sys Admin on this platform since 1984 and have
never personally seen this.
