[rabbitmq-discuss] Heartbeat vs timeout in .NET code

[Arun Rao]

Sorry guys for extending this topic further and further. What if I disabled
heartbeat?

*On the producer side *- When a producer tries to send a message, .NET
client code will catch Connection Shutdown exception and try to reinitiate
the connection. Depending on the traffic on the connection, this could be
caught within a second if the connection was active sending data or within
several minutes if the connection was idle.

*On the consumer side* - How frequently does the consumer check the queue
for messages? I thought that even without heartbeats Consumers will catch
the following exception:

System.IO.IOException: Unable to read data from the transport connection:
An existing connection was forcibly closed by the remote host. --->
System.Net.Sockets.SocketException: An existing connection was forcibly
closed by the remote host
   at System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset,
Int32 size)
   --- End of inner exception stack trace ---
   at RabbitMQ.Client.Impl.Frame.ReadFrom(NetworkBinaryReader reader)
   at RabbitMQ.Client.Impl.SocketFrameHandler_0_9.ReadFrame()
   at RabbitMQ.Client.Impl.ConnectionBase.MainLoopIteration()
   at RabbitMQ.Client.Impl.ConnectionBase.MainLoop()

Thanks!
