Local fix
Problem summary
**************************************************************** USERS AFFECTED: Users of the status MQCLI control command, REST API interface, or Appliance Web UI may be affected by this issue. Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: IBM MQ keeps an internal record of how much memory each thread has allocated and this value is used to determine the value that is exposed via the MQCLI status command, the REST API interface, and the Appliance Web UI Queue Manager Status view. Some IBM MQ threads recorded this number as a negative value and so the status command showed incorrect information about the memory that a queue manager was using.
Problem conclusion
The IBM MQ code has been modified to ignore negative values when calculating the total memory usage. A programming error has also been corrected where the structure used to record the memory usage for an IBM MQ thread was being incorrectly reused across thread instances without first being cleared. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v8.0 8.0.0.12 v9.1 CD 9.1.1 v9.1 LTS 9.1.0.1 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 ---------------------------------------------------------------
