APAR status

  • Closed as program error.

Error description

  • The following FDC from the same process is generated every
second:

Probe Id          :- XC401010
Component         :- xcsWriteQmgrLogMessage
Program Name      :- amqrmppa
Major Errorcode   :- xecX_W_DAEMON_UNAVAILABLE
---------------------------------------------------
MQM Function Stack
ccxResponder
rrxResponder
rrxReportError
xcsDisplayMessageForSubpool
xcsWriteQmgrLogMessage
xcsFFST

This behaviour is unexpected. When the error log daemon is
unable to process an error message request because of too many
requests, then it should only generate the FDC every 60 seconds,
not every second.
