Problem summary
**************************************************************** USERS AFFECTED: Users of IBM MQ client applications which attempt to reconnect and reuse a broken connection handle mutliple times. Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: When a reconnectable IBM MQ client experiences a MQRC_CONNECTION_BROKEN error, it then issues a new MQCONNX call on the same thread with the HCONN that exists from the previous connection. During this process an error in the MQ client code caused it to invalidate some internal information in the client's internal channel status table. On subsequent reconnection attempts, this status information caused an invalid memory access, which generated the FDC file and caused the connection attempt to fail.
Problem conclusion
The MQ client code has been corrected to prevent invalidating the information in the internal channel status table. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v8.0 8.0.0.6 v9.0 LTS 9.0.0.5 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 ---------------------------------------------------------------
