Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When DB2 is unable to respond to collect calls, the collect call
  will time out. This will redrive connect calls between the agent
  and the OMPE server. The TCB for the collect call that timed out
  effectively is orphaned. Below the line storage in the OMPE
  server task will be consumed and the task may encounter storage
  related abends; 80A, 878...
  
  Evidence of this can be noted by numerous occurrences of the
  below messages

  PROBLEM SUMMARY:
  If a DB2 system is incapable of honoring requests for data
  within the time period specified by COMMCOLL STIMER, the
  connection between the agent and OMPE server for that DB2
  system can get broken and re-established many times, as
  indicated in the RKLVLOG.  Some system storage and private
  storage within OMPE server becomes exhausted, resulting in
  S878 and S80A abends within the OMPE server and other
  address spaces.
  
  Also, numerous "Error 4 getting AVT pointer for DB2"
  messages in RKLVLOG when DB2 system(s) that a situation is
  distributed to are not operational.
  
  PROBLEM CONCLUSION:
  Allow the agent / OMPE server connection to remain intact after
  a data collection time-out.
  
  Change print of "Error 4 getting AVT pointer for DB2" messages
  in RKLVLOG such that when KBB_RAS1=ERROR, they do not show.
  They will show when KBB_RAS1=ALL.
