Description

StreamMessage.deserialize (StreamMessage.java:63) function return null when receive end of stream for ReadableByteChannel.read () function. IncomingMessageHandler.run (ConnectionHandler.java:257) interpreting null - as unsupported message and ignore it. It resulting infinite loop when IncomingMessageHandler try to read message from closed steram, and deserialize always return null - to indicate close stream.

It not happen on normal socket, because when normal socket closed it throw IOException. But happen from time to time when iner-node ssl encryption enabled.

I'm attach two tread dump from one node with two infinity lopped thread with id 614 and 583
