****************************************************************
In the reported problem, an application was performing HBRxxx
calls for the ILOG product.  Each HBRxxxx call executed code
within a CICS TRUE, which used CHANNEL and CONTAINER resources.
Various CHANNEL and CONTAINER control blocks were not
FREEMAINed, thereby causing a memory leak.

    



Problem conclusion


    

  • DFHPGEX has been modified to ensure CHANNEL and CONTAINER
control blocks associated with TRUE processing, are now
FREEMAINed.
