Problem summary
**************************************************************** USERS AFFECTED: IBM MQ publish/subscribe messaging users. Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: A coding error with the queue manager's publish subscribe messaging code could cause the queue manager to attempt to deliver a message to a queue which had recently been deleted. State information regarding the subscription associated with the deleted queue was not correctly updated on an unsubscribe operation. This then caused the queue manager to make the illegal memory access (SIGSEGV) reported in the FDC.
Problem conclusion
The coding error has been corrected to ensure that the state information is updated correctly during the unsubscribe operation. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v7.5 7.5.0.9 v8.0 8.0.0.9 v9.0 CD 9.0.5 v9.0 LTS 9.0.0.3 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 ---------------------------------------------------------------
