PM38162: IMS PA LOOP CAUSED BY TRYING TO ACQUIRE WORKING STORAGE THAT IS NOT AVAILABLE

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When IMS PA exhausts available storage for internal transit
  queues it attempts to flush 'old' records.  When there is only
  1 transaction, and it is current, no "flushing" occurs, but a
  a request to obtain storage for the new record is still
  attempted and fails, causing a loop.  Note that the 1
  transaction may use several hundred megabytes of trace data.
  This only affects IMS PA users reporting from OMEGAMON ATF
  journals.
