APAR status
Closed as program error.
Error description
Creating extremely short-lived TCP connections generated AMQ9213E errors in the queue manager error log. Many undesirable errors would be generated in situations such as third party Linux HA solutions that generate very fast TCP connections and then disconnect them, just to see if the remote machine is still alive.
Local fix
Problem summary
**************************************************************** USERS AFFECTED: Any users creating short-lived TCP connections to MQ listeners Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: Undesirable error messages were generated in situations where a TCP connection is made and disconnected extremely quickly, causing a build up and backlog of error messages. There was no need to generate such an error message so early on in the TCP processing.
Problem conclusion
The code has been changed so that the error message is not generated in the case that the connection is lost very quickly after it is begun. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level 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 ---------------------------------------------------------------
