WebSphere® MQ event notification for situations using the MQSeries_Events attribute group is delayed until the WebSphere MQ Monitoring agent is fully online.
Because the maximum number of events that can be retained is reached, the agent no longer retains the oldest event for each new event that it intercepts.
This message can occur at startup when the event queues of the monitored queue manager have many back-logged event messages. Determine the reason for either the inability of the WebSphere MQ Monitoring agent to come online or the loss of online status of it, and correct the problem.
This error might occur as the result of a communication failure with the Tivoli® Enterprise Monitoring Server. If this is a new monitoring environment, you might need to change the values of communication parameters such as CTIRA_CELL_NAME. If the problem persists, contact IBM Software Support.
