Problem summary
**************************************************************** USERS AFFECTED: Users running MQ applications which often connect and disconnect from the queue manager will be most likely to be affected by this problem. Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: A small timing window meant that it was possible for the MQ queue manager agent process (amqzlaa0) could fail to correctly handle the error case where an interprocess communication pipe had timed out and expired.
Problem conclusion
The MQ agent process has been modified to appropriately handle the timeout in the MQ IPCC pipe. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v8.0 8.0.0.5 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 ---------------------------------------------------------------
