No, the error does not occur when you right click something. The connection is closed earlier (as RabbitMQ.Client.Exceptions.AlreadyClosedException indicates), and without a log snippet from the server plus a piece of code that demonstrates what your application does, we would not be able to suggest anything more specific.

We do not guess in this community.

What is particularly confusing is that the exception seemingly originates in RabbitMQ.Client.Impl.SessionManager.Lookup(Int32 number) but the provided value is a string.

Please put together a small executable example that reproduces the problem and publish it on GitHub so that the maintainers of this client could take a traffic capture and troubleshoot further.
