Re: Mysterious MCH3601 errors at V4R3M0

Hans,

I have an ILE RPG program that is a registered exit program for one of the
VI/400 exit points. It is called with 4 parameters. It is called MANY times
every day. For the first 6 weeks after implementation it ran without
failure. Since then it has experienced intermittent failures. Sometimes
several times a day, sometimes only every 3-4 days. The failure is always
the same. MCH3601. It always occurs on the first line of executable code.

C                 MOVE   PARM3    DATASTRUCTURE

PARM3 is unreferenced.

Any good ideas would be greatly appreciated.
