  Failed requests for memory did not fully terminate a log reader
  task that was about to be started causing failures during
  subsequent log fetch requests.
  Incorrect CSECT reporting for DSNLXLLM.DSNLJMLR and
  DSNLXLLM.DSNLJMCF due to missing MEPL entry.

  IDAAV7R5/K
  

Problem conclusion

• Code has been changed to terminate log reader tasks correctly
  after any memory request failure. Missing CSECTs were added to
  MEPL.
