Error description

  • In either ISPF or if you use IPCS via batch, the VERBX DFHPD750
    'PG=3' command results in a Abend SA78-X'10'.
    The dump shows:  module BLSRVEC3 offset X'191D6': Abend
    SA78-X'10'.
    
    This is due to CICS module DFHPGDUF doing a "double FREEMAIN" of
    its EP_LIST_TOKEN.

    or " IPCS VERBX DFHPD750 'PG' "
    and sees an ABENDA78 - 10 abend due to the dump
    formatter issuing two STORAGE(RELEASE) calls, specifying

    call from being made.
