Closed as program error.
Error description
The MQGET in an MQ client should wait for a complete message to arrive before MQGET returns to the application. However, during a client reconnect, because of an inadequate internal state check, MQGET then returned immediately, even though the complete message had not been received from the server. The result was that the application saw only part of the message.
Local fix
Problem summary
**************************************************************** USERS AFFECTED: Client applications that are receiving messages where a client reconnect may occur. Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: Insufficient checking was being performed in the MQ client library code when reconnect processing occurred at the same time as a message was being delivered to the client.
Problem conclusion
The product has been corrected so that a partial message cannot be returned through MQGET in these circumstances. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v9.1 LTS 9.1.0.10 v9.2 LTS 9.2.0.5 v9.x CD 9.2.3 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 ---------------------------------------------------------------
