Problem summary
**************************************************************** USERS AFFECTED: This issue affects users of MQ client applications which use the asynchronous consume functionality to retrieve messages from a queue. Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: Under certain circumstances the queue manager incorrectly copied memory between two overlapping buffers which led to a corruption of a message's MQMD data. The corrupt MQMD was sent to the client which detected the corruption and reported an internal error.
Problem conclusion
The MQ code within the queue manager has been updated to prevent this invalid memory copy. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v9.0 CD 9.0.4 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 ---------------------------------------------------------------
