I'm new to Akka; had a local actor system talking to a remote system on another machine in our network just fine for a couple of days, and then it just stopped working for reasons I've not been able to fathom.
I'm aware that the severing of an association isn't necessarily a problem (#6 at http://petabridge.com/blog/top-7-akkadotnet-stumbling-blocks/), but in my case it's definitely not something that should be happening. I'm unable to get the result of any work that I want performed by the remote actor, and when I log onto the remote machine and look at its output, I'm not seeing any of the messages acknowledging receipt of a request that I coded it to print to its console.
This is what I'm seeing on the remote machine, as soon as I spawn the actor and deploy it to the remote machine (spawne myActorSystem actorName <@ expression @> [ SpawnOption.Deploy (Akka.Actor.Deploy (RemoteScope parsedAddress)) ]):
( See output at http://www.miloonline.net/stash/akka_remote_error.txt )
My local system's configuration is:
sprintf
"""akka {
actor {
provider = "Akka.Remote.RemoteActorRefProvider, Akka.Remote"
serializers {
wire = "Akka.Serialization.WireSerializer, Akka.Serialization.Wire"
}
serialization-bindings {
"System.Object" = wire
}
}
remote {
helios.tcp {
hostname = %s
port = 0 // Auto-configure port
}
}
}"""
(Net.Dns.GetHostName ())
... and on the remote machine:
sprintf
"""akka {
actor {
provider = "Akka.Remote.RemoteActorRefProvider, Akka.Remote"
serializers {
wire = "Akka.Serialization.WireSerializer, Akka.Serialization.Wire"
}
serialization-bindings {
"System.Object" = wire
}
}
remote {
helios.tcp {
hostname = %s
port = 1234
}
}
}"""
(Net.Dns.GetHostName ())
Again, these worked fine for two or three days; I've pored over my code changes in Git, and there's is nothing that would explain the sudden and persistent failure.
EDIT: Originally, I had the remote block of the HOCON configuration inside the actor block on my local machine. I moved that out of the actor block, and now the output on the remote machine has changed (I've edited the blockquote of the remote output to reflect this). I'm still seeing errors, though, and my attempts to have the remote actor do work and send back a value are still failing.
EDIT: I've moved my remote actor system over to a Windows Server machine, which has eliminated the former SocketException errors. Unfortunately, the problem I'm having now is that after my remote system communicates with my local system just fine for one session, it never works again after I terminate the remote process. Any and all succeeding attempts to establish the exact same set-up result in the familiar EndpointDisassociatedException failures, even after I reboot both machines. (As indicated above, see http://www.miloonline.net/stash/akka_remote_error.txt for the output from the remote actor system.) Is there some standardized means of terminating or instantiating an actor system that would address this issue?
