Error description

• Dump Title: OMEGAMON II FOR DB2: COMPID=5655OPE00, JOB=O2CI19  ,
  LMOD=KO2OCNTB#L, CSECT=O2ORCV  , OFFSET=00125E
  ABEND0C4-10 KO2ORCVB+125E (PK44284) on a D5031000A29A (CLC)
  instruction, R1 bad.  While processing a program check due to
  a wild branch, KO2ORCVB itself programs checks trying to
  determine the location of the PSW.  Using R5 to point to the
  PSW/REGs save area (RECDEBUG), it does a LOAD into R1 and then
  tries to access that storage using R1.  This leads to yet
  another program check and an unnecessary and misleading SVC
  DUMP.

  PROBLEM SUMMARY:
  During recovery processing, an unnecessary dump may be
  generated with the following title: OMEGAMON II FOR DB2:
  COMPID=5655OPE00, JOB=XXXXXXXX, LMOD=KO2OCNTBL#,
  CSECT=O2ORCV, OFFSET=0012C2
  
  PROBLEM CONCLUSION:
  When checking the abending PSW address, the recovery code
  was not first validating  the accessability of the PSW
  itself. The case of a bad PSW (from a bad branch) was not
  being handled properly.
  

Problem conclusion
