PH36641: DFHSJ1009 "A TASK RUNNING IN A JVMSERVER HAS TRIGGERED A RUNAWAY CONDITION" ALWAYS HAS CJSL TRANID VS THE ACTUAL RUNAWAY TRANID.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• This message is thrown and the tranid shows CSJL, which is not
  the task that was detected as runaway;
  
  DFHSJ1009 W date time
  applid tranid trannum JVMSERVER jvmserver is being disabled and
  restarted by CICS because a task running in a JVMSERVER has
  triggered a runaway condition, leaving the JVMSERVER in an
  inconsistent state.
  
  When DFHSJ1009 occurs CICS attempts a PHASEOUT. Then after a
  delay CICS does a PURGE which typically would cause programs
  looping to get a ThreadDeath, which would turn AKC3 abend which
  would identify the runaway transaction in the log. However, in
  the case where the transaction is behaving normally, such as a
  long running task, it may not abend and there is nothing in the
  log indicating which transaction triggered the runaway.
  
  This APAR is to update DFHSJ1009 to include the transaction
  that triggered the runaway.

  A task running in a JVMSERVER triggers a CICS runaway condition
  and issues message DFHSJ1009, however it is of limited use when
  it comes to diagnosing which task it was that caused the
  runaway.  A dump and trace need to be examined to identify the
  offending task.

Problem conclusion

• A new message DFHSJ1010 will now be issued when a task running
  in a JVMSERVER triggers a runaway condition. Message DFHSJ1010
  will include both the transaction number and taskid causing
  the runaway.
  
  A new message will be added to CICS Transaction Server for z/OS
  5.5 and 5.6 Documentation:
  
  DFHSJ1010 W  date time applid tranid trannum JVMSERVER jvmserver
  is being disabled and restarted by CICS because taskname task
  tasknum running in the JVMSERVER has triggered a runaway
  condition, leaving the JVMSERVER in an inconsistent state.
  
  Explanation
  
  JVMSERVER jvmserver is being restarted by CICS because it is in
  an inconsistent state. A task runaway condition has occured,
  leaving the JVM in an inconsistent state.
  
  System action
  
  CICS disables the JVMSERVER resource with the PHASEOUT option to
  allow existing work in the JVM to complete where possible and
  prevent new work from using the JVM. After the JVMSERVER is
  successfully disabled, message DFHSJ1008 is issued. CICS
  attempts to re-enable the resource to create a new JVM.
  
  User response
  
  Determine why the task triggered runaway processing.
