  ANALYSIS:
  This ABEND S0C9 can occur in JES2 V2R3 when JES2 is in
  initializion processing at the top of the hour (hh:00).
  
  While the 0C9 occurs in HASPMISC, the issue occurs in module
  HASJSPLR.
  
  In the JES2MON sampling procedure JSMSMPLR near label JSMSTART,
  a check is perfomed to see if we are at the top of the hour, and
  if so, get a new $LMD with $CALL GETLMD.
  
  This new $LMD becomes the current $LMD on the chain, and its
  fields are in their initial states.
  
  If this is still the current $LMD when JSMSMPLR detects that
  JES2 is in initialization (near JSMSTINI) we will skip limit
  processing when we reach JSMSTART. In the process, we do not set
  the field LMDSSAMP.
  
  Later, when we perform a BLDSMF84 in HASPMISC, LMDSSAMP is used
  as the divisor in a calculation and the 0C9 (division by 0)
  occurs (after BS84BL21).
  
  KNOWN IMPACT:
  $HASP095 JES2 CATASTROPHIC ABEND. CODE = S0C9
  --However, JES2 recovers with--
  $HASP072 RECOVERY IN PROGRESS
  $HASP073 RECOVERY SUCCESSFUL - NORMAL PROCESSING RESUMES
  
  VERIFICATION STEPS:
  1. JES2 V2R3
  2. JES2 was in initialization at the top of the hour
  3. SMF Records are enabled.
  4. $HASP095 JES2 CATASTROPHIC ABEND.  CODE = S0C9  (RC =
     00000009)
  5. Dump analysis will show the current $LMD has
     +0028  LMDSTCKE. 00000000  00000000  00000000  00000000
            01/01/1900 00:00:00.000000
     +0800  LMDSSAMP. 00000000
     R4 will have address of current $LMD in 64-bit storage

  ****************************************************************
  ABENDS0C9 in HASPMISC because computation for SMF data did not
  take into account that there may have been zero events seen.
  

Problem conclusion

• TYPE/RESTART (HOT) IPL/REQUIRED(NO) CLPA(NO)
  
  Logic updated to check for number of SMF events being zero.
