Problem summary
**************************************************************** USERS AFFECTED: You may be impacted by this problem if you are using MQ asynchronous consume and messages with message properties are being got, and those properties have been requested to be stripped out of the message, but the resultant required buffer is larger than 8k. Platforms affected: MultiPlatform **************************************************************** PROBLEM SUMMARY: If the message data is too big to fit in the standard 8k buffer with the message properties in, but the application has asked for them to be stripped out, and that will fit, then MQ temporarily allocates a bigger buffer. However, MQ fails to free the temporary buffer.
Problem conclusion
The fix is to ensure that a temporary buffer, if it has been allocated, is ultimately freed. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v7.0 7.0.1.12 v7.1 7.1.0.5 v7.5 7.5.0.4 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 ---------------------------------------------------------------
