1.       What is the reason of error “DeadReferenceError: Calling Stale Broker”?
My program uses PB inside loopback, so I shouldn’t have any disconnects. 

It means something disconnected.  Disconnects can happen for many reasons; perhaps your process terminated, perhaps an unhandled exception caused a problem.

2.       I call many time remote method returning pb.Referenceable. Can it be a reason of topic 1 or generally lead to system’s degradation?

That should be fine. But I can't see your code, so I have no idea what you mean by "many time".  If you can provide a *short* example of a program with this problem (not your whole program, just the shortest one that works), we might be able to help more.
