  * PROBLEM DESCRIPTION: An Out of Memory error occurs from      *
  *                      com.ibm.ws.gridcontainer.parallel.impl. *

  *                      while logging SubJob logs into the      *

  ****************************************************************
  When a sub job completes, the top level job is notified and
  retrieves information and the logs from the subjob to be
  displayed in the top level job log.  If large amounts of
  debugging is being used in the batch application, this can
  cause many sub job log parts to be created.  When these parts
  are retrieved by the top level job into a String as a buffer,
  this can result in a  â??java.lang.OutOfMemoryError: Java heap
  spaceâ?? error when the resulting String is formed.
  

Problem conclusion

• A code update has been done to counter this issue. A new
  WebSphere variable has been created,
  â??TLJ_DISPLAY_SUBJOB_LOGSâ??, which can hold one of three value
  The possible values are, â??DISPLAY_SUBJOB_LOGS_SYSOUTâ??,
  â??DISPLAY_SUBJOB_LOGS_JOBLOG_ONLYâ?? and
  â??DISPLAY_SUBJOB_LOGS_NOWHEREâ??. Now the user has the option t
  whether display subJob logs in Sysout or Job logs, or not
  display the Subjob logs at all.
  
  The fix for this APAR is targeted for inclusion in fix pack
  8.5.5.27 and 9.0.5.21. For more information, see 'Recommended
