Error description
When opening a queue manager's DEFXMITQ on an MQ Queue Manager that has activity trace enabled, a failure data capture (FDC) record is generated, reporting SIGSEGV or access violation occurs and the activity trace is not be written.
Local fix
Disabling activity trace will stop the FDCs from being generated.
Problem summary
**************************************************************** USERS AFFECTED: Users who have a configuration which opens a defined DEFXMITQ on their Queue Manager and have activity trace enabled. Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: In the MQ queue resolution routines, if the specified queue cannot be resolved to its target queue manager, the DEFXMITQ (if defined)is used to hold the message. When opening this queue, if Activity Trace was enabled, an FDC record would be written due to an Access Violation on the Queue Manager.
Problem conclusion
The code has been updated so the access violation no longer occurs in this scenario. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v8.0 8.0.0.12 v9.0 LTS 9.0.0.6 v9.1 CD 9.1.2 v9.1 LTS 9.1.0.2 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 ---------------------------------------------------------------
