In the SP2 readme notes, there is a new broker setting:
Allow for multiple client connections to be opened to the Broker
from the Integration Server to enhance performance. To specify
the number of client connections, set the following property in
the config/server.cnf file:
watt.server.broker.producer.multiclient=X
Are you using this setting? If so, remove the setting, restart the IS and Broker and see if you still have the problem. We had the problem and I think that we removed this setting.
