    The problem may be summarized as follows:
    1. An HPR connection is established.
    2. A path switch starts.
    3. RCM sends a Route Setup GDS signal to the partner.
    4. RCM receives a Route Setup Reply GDS signal.
    5. RCM allocates 2 pieces of storage in order to pass the
       CV67s from the GDS signal to RTP.
    6. RTP only frees 1 of the pieces of storage.
    7. Over time, this leads to a growth in storage.
    

Problem conclusion

  • ISTRPCRO is updated to free the storage associated with
    the forward CV67.
    
    ISTRPCRT is included for maintenance purposes only.
