The WebSphere® MQ Monitoring agent data-collection component exceeds the MAXHANDLES value (maximum number of handles that can be held by a single task) for the queue manager specified by the mgrname value. Data collection for queues in the indicated queue manager cannot be completed.
Data for some queues is not available for display. WebSphere MQ Monitoring agent requires that you monitor the MAXHANDLES value for the number of queues that you have defined to each queue manager plus a fixed overhead of three queues.
Issue an ALTER QMGR MAXHANDS(nnnn) command to the queue manager, where nnnn is greater than or equal to the number of queues that are defined to that queue manager plus 3.
