APAR status

• Closed as program error.

Error description

• In the APARed case Development finds the CHINIT called CSFPPRF
  as it required re-generation of pseudo-random numbers. The call
  to CSFPPRF failed with RC=8, reason=00003E80, i.e. a RACF
  permissions failure. The CSQX571E error is reported in
  xrnEntropyRead. The MQ rrcE_PKCS11_BAD_RETURN_CODE return code
  is then passed up the stack to rriAcceptSessReceive.
  rriAcceptSessReceive doesn't anticipate any failures along this
  path so sets its local RC to rrcE_UNEXPECTED_RETURN_CODE.
  rrxResponder detects this error and calls the message-issuing
  logic to process the return code. The message-issuing code
  determines that this return code requires an abend, so abends
  S5C6-00E70546. The failure when calling CSFPPRF was detected
  and message CSQX571E was issued, but this shouldn't result in
  the subsequent S5C6-00E70546 abend.
  

Local fix

• In this case resolve the RACF permissions problem to prevent
  this problem from occurring again.

  ****************************************************************
  A 5C6-00E70546 abend is seen shortly after message CSQX571E is
  printed in the channel initiator job logs.
  
  The CSQX571E message is printed when a call to CSFPPRF is made
  for the re-generation of pseudo-random numbers and fails.
  CSQX571E contains the return code and reason code as to why the
  call to CSFPPRF failed which can be used to resolve the problem
  for the next time CSFPPRF is called in the same way.
  
  MQ internally treats the failed CSFPPRF call as unexpected and
  as a result the 5C6-00E70546 abend and dump is taken
  unnecessarily.
  

Problem conclusion

• The code has been updated so the 5C6-00E70546 abend and dump is
  not taken after a failed call to CSFPPRF and CSQX571E is
  printed.
