We have a never ending RPG program that processes incoming

I added code to clean up old objects (Garbage Collection) as this
had not been done. I thought this might help as I noticed that the
amount of memory consumed by the job was less than before. It must be
something to do with the increased volume but where else to look ?.
In time we will as with all our systems be converting to full java ,
but that is still some time off so any help appreciated.

FWiW: If the problem is perceived to be _not_ with the Java code failing to effect proper cleanup, but instead presumed to be something with the language(s) involved, then search the APAR database for the TMPSTGLK keyword [there should be a specific document with a list of all known defects for that symptom kwd], for the release being used; unstated, though past messages suggest possibly still v6r1. For example, in v5r2, there was an issue with the RPG for its interface to Java that had a memory leak problem corrected by a PTF.
