Major Description
SystemUsage.sendFailIfNoSpace results in an exception. this exception will cause a network bridge to stop and restart, just like an network outage. Handling it does not make sense as the only way to handle it is to stop and start an individual consumer on the bridge, to stop consumption, which is effectivly what blocking the send on the broker would do, the default when sendFailIfNoSpace=false. Coupled with the fix for https://issues.apache.org/jira/browse/AMQ-3331, blocking behavior is the best for a network connector.
