Error description
Memory usage of the IBM MQ amqzlaa0 process may be seen to rise over time in an uncontrolled manner. If corrective action is not taken then free memory on the system may become exhausted.
Local fix
Applications should disconnect cleanly using MQDISC
Problem summary
**************************************************************** USERS AFFECTED: Users of activity trace that have applications which do not cleanly disconnect may be affected by this problem Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: Some memory was allocated by the activity trace functionality while an application was connected to the queue manager. This application ended without disconnecting from the queue manager and the memory allocated by the activity trace functionality was leaked.
Problem conclusion
The code is corrected so that all memory that is allocated by the activity trace functionality is freed when cleanup processing takes place for applications that end without disconnecting from the queue manager. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v7.5 7.5.0.8 v8.0 8.0.0.7 v9.0 CD 9.0.3 v9.0 LTS 9.0.0.2 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 ---------------------------------------------------------------
