Issues shutting down actor system

[yeowgit]

Hi,

I am having problem shutting down my actor system with remote dispatcher thread lingering. I call system.Terminate().Wait() when stopping my service.

This is on Akka v1.3.2

Debug logs as below when shutting down: [DEBUG NLogLogger] received AutoReceiveMessage : [akka://Executioner/user] - ExistenceConfirmed=True [INFO NLogLogger] Shutting down remote daemon. [INFO NLogLogger] Remote daemon shut down; proceeding with flushing remote transports. [DEBUG NLogLogger] now watched by [akka://Executioner/temp/u] [DEBUG NLogLogger] received AutoReceiveMessage [DEBUG NLogLogger] Stopped [INFO NLogLogger] Remoting shut down [INFO NLogLogger] Remoting shut down.

I distinctly remember we had this issue with Helios a long while back. But A: we fixed that, and B: We moved to DotNetty as our default network transport.

I think this issue was fixed even before 1.3.2. But can you update to 1.3.3 and make sure you use the DotNetty transport?

[yeowgit]

That seems to fix it.
