PM81186: ABEND0C1 OR S0C4 MAY OCCUR WHEN MORE THAN ONE SUBTASK IS IN USE IN THE TARGET JOB.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• AbendS0C1 or S0C4 may occur when more than one subtask is in
  use in the target job and log apply is processing multiple pages
  concurrently.
  Access to a linked list of logs used by all subtasks is not
  single threaded.  This can result in the list being corrupted,
  which in turn can result in an ABEND S0C1 or S0C4. The code will
  be changed to single thread access to the list.
  

Local fix

• Rerun the failing job with MAX-SUBTASK=1.
