Error description
Browsing messages on queues with IBM MQ Explorer increases commit size memory each time the queue is browsed. This memory is not released and continues to grow each time a queue is browsed or refreshed.
Local fix
Problem summary
**************************************************************** USERS AFFECTED: All users of IBM MQ Explorer making use of the browse queue functionality. Platforms affected: Linux on Power, Linux on S390, Linux on x86, Linux on x86-64, Linux on zSeries, Windows **************************************************************** PROBLEM DESCRIPTION: When the browse dialog was closed the objects it contained were not made eligible for garbage collection due to a circular memory reference. Because the objects were never garbage collected by the JVM each invocation of the browse dialog would cause the memory usage of the IBM MQ Explorer to increase.
Problem conclusion
The circular reference has been removed, thereby making the objects which back the browse dialog eligible for garbage collection. This causes the memory used to be reduced when the JVM runs the garbage collector. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v7.5 7.5.0.8 v8.0 8.0.0.6 v9.0 CD 9.0.2 v9.0 LTS 9.0.0.1 The latest available maintenance can be obtained from 'WebSphere MQ Recommended Fixes' http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg27006037 If the maintenance level is not yet available information on its planned availability can be found in 'WebSphere MQ Planned Maintenance Release Dates' http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg27006309 ---------------------------------------------------------------
