Problem summary
**************************************************************** USERS AFFECTED: Users of WebSphere MQ 7.5 using publish/subscribe messaging Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: A logic error in the publish/subscribe broker within the MQ queue manager presented a timing window which could cause a subscription lock count to be recorded incorrectly. This would then mean that the lock was not fully released, which would in turn prevent the MQCLOSE operation associated with that subscription from completing successfully, resulting an FDC record with probe id XC514090 xecL_W_LONG_LOCK_WAIT.
Problem conclusion
The lock count mechanism within the publish/subscibe broker of the MQ queue manager has been corrected. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v7.5 7.5.0.8 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 ---------------------------------------------------------------
