Hello hAkkers.
I've strange problems with mentioned upgrade. Communication with remote 
actors work but only partially. There are two components that talk to each 
other via remoting. Here is excerpt from the logs.

Portal:

and here is database:

[WARN] [06/10/2014 20:00:00.197] 
[new-scribe-system-akka.remote.default-remote-dispatcher-24] 
[akka.tcp://[email protected]:5225/system/endpointManager/reliableEndpointWriter-akka.tcp%3A%2F%2FQLP-SCRIBE-CLIENT%4010.101.159.54%3A5225-1]
 
Association with remote system 
[akka.tcp://[email protected]:5225] has failed, address is 
now gated for [5000] ms. Reason is: [Disassociated].

What I figured out so far it seems that they try to communicate via local 
address. Not public. This is deployed on Amazon AWS, locally it works fine. 
What's also interesting is that some messages do work but some do not. I 
ran that locally with exact same data and it worked. 

Last but not least I'm not sure if that is a feature or a bug (for me it is 
a bug) but host name resolution doesn't work well with Akka remoting. If I 
have one node that is configured to listen on specific address A then if 
message arrive on another interface but on the same host it doesn't work. 
Even localhost vs. 127.0.0.1 fails with log message that it wasn't targeted 
to "me".

Sorry for lengthy post. I hope someone can chime in and help.
