[rabbitmq-discuss] C# v2.7.1 Client Unhandled Exceptions

[Simone Busoli]

Hi Bryan, I think it's a known bug which has popped up on the list some

has been filed already. It's indeed related to heartbeat settings.
The thread was titled "Possible bug when disposing connections in .NET
client 2.7.0/1"
