Synchronization
StreamServer uses MQGMO_SYNCPOINT to make sure the message remains in the queue if the WebSphere MQ input connector fails to read a message. The WebSphere MQ input connector retries to read the message until it succeeds to do so. If it continuously fails to read the message, you must remove the message from the queue by using WebSphere administration tools.
