[jira] Created: (QPID-1345) Flow control has changed to the Credit
Manager level not the Channel level so new subscriptions do not suspend
causing excessive CPU usage.

Key: QPID-1345
URL: https://issues.apache.org/jira/browse/QPID-1345
Project: Qpid
Issue Type: Bug
Components: Java Broker
Affects Versions: M3
Reporter: Martin Ritchie
Summary:
Creating a subscription on a flow controlled session with messages to deliver
will cause the broker to spin. The Credit Manager is suspended and so will not
notify the newly Active Subscription that it should Suspend. There for the processQueue loop will continue to attempt delivery to that ACTIVE subscription despite the lack of credit.
