I encounter the problem when weblogic connect to MQ , I check the MQ and weblogic are running and try to stop both service and start up again. However the problem still persist.
The problem looks like it's on the MQSeries side, or in between (a blocking firewall), or a configuration error on your part (incorrect MQ Series URL?).
Googling 'mq closure reason = 2009' yields this page for common reasons MQSeries throws this error: https://www-01.ibm.com/support/docview.wss?uid=swg21472342
