Error description
FDC issued- Probe Id :- CO628001 Component :- ccxStageReAlloc Program Name :- amqrmppa Major Errorcode :- rrcE_BAD_PARAMETER Probe Description :- AMQ6125E: An internal IBM MQ error has occurred.

This assumption is only correct when sharing conversations is negotiated to 1 or higher.

Problem summary
**************************************************************** USERS AFFECTED: Any user with clients that connect to a queue manager using a non-multiplexed channel connection may be affected. Platforms affected: AIX, IBM iSeries, Linux on Power, Linux on S390, Linux on x86-64, Linux on zSeries, Solaris x86-64, Solaris SPARC, Windows **************************************************************** PROBLEM DESCRIPTION: An MQ client may cause a queue manager to need to resize a staging area buffer to handle the response of an MQI call. This may be needed where an MQI call returns a larger response than its request, the MQGET API is an example of such a call. The code that resizes the staging area on the queue manager side of the connection makes an invalid assumption that the connection is always using a multiplexed connection and incorrectly issues an FFST indicating a bad parameter.
Problem conclusion
The buffer reallocation code that assumes a multiplexed connection is being used on the server is corrected to permit both multiplexed and non-multiplexed connections. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v9.1 CD 9.1.3 v9.1 LTS 9.1.0.3 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 ---------------------------------------------------------------
