APAR status
Closed as program error.
Error description
The management concentrator must listen to connection.closed and connection.failed notifications emitted by the MBeanServer to clean up obsolete or broken JMX connections and listeners (from its cache of known or discovered MBean URLs). This might be problematic with a large deployment where JMX connections might get closed and fail often, leading to a large list of obsolete listeners that are kept in the cache collection and are traversed during normal ManagementConcentrator operations.
Local fix
