As this can be easily worked around in the application I'm lowering the severity and re-targetting for after 1.1.1 due to time constraints. *** Bug 453650 has been marked as a duplicate of this bug. *** The error that the email thread quoted above is based on refers to warnings in the logs for *incoming* frames that are ignored. This is a result of not cancelling subscriptions (or not waiting for the cancellation to be confirmed) before closing the connection. An explicit sync() is recommended as it allows any exceptions to be handled (e.g. the in doubt transfer may be invalid of may breach a queue limit). |

In addition to sync() we should set timeout to 0 to ensure clean close of the session.
