APAR status

• Closed as program error.

Error description

• This APAR addresses and corrects three problems:
  1)  ABEND0C4-11 KOBSUBXM+1158 (at Base level - 10/28/08
       HKOB620)
   2)  Ensuing loop involving KO2OINTB with an ABENDA78-10
   3)  High CPU
  ABEND0C4-11 KOBSUBXM+1158 on a 58403000 (Load) instruction with
  R3 bad.  KOBSUBXM tries to free a MODULE from the IMVT (Install
  Module Vector Table) and storage had already been FREEd.  This
  leads to the program check.  Messages issued during this time
  include:
   OMEGAMON:   >> OB0930: Unexpected Program Check - SUBX+1158 <<

   IEA794I SVC DUMP HAS CAPTURED:  793
   DUMPID=038 REQUESTED BY JOB (O2CI    )
   DUMP TITLE=OMEGAMON II FOR DB2: COMPID=5655OPE00, JOB=O2CI    ,
               LMOD=KOBAS510#L, CSECT=UNKNOWN , OFFSET=02C038
  Following this, the same task (TCB) issues a FREEMAIN in
  KO2OINTB+CC62 (at PK91678 level) to free a register save area.
  The address passed on the SVC 78 (0A78) was bad and led to an
  ABENDA78-10.  Control was passed to KO2OINTB's ESTAE retry
  routine.  KO2OINTB reloads the retry registers and reissues the
  FREEMAIN.  This again results in an ABENDA78 and a LOOP begins.
  KO2OINTB is unaware of the LOOP and Omegamon LOOPs until taken
  down.
