When reading web socket data, the loop will run forever if there is no more data available in a chunk. This fix will add a counter to how many times it tries to read before a timeout is reached.
Fixed a problem where the constructor parameter for permission_filter was not being fulfilled. This can cause a crash also leading to the read of web socket data to begin looping.
Added better debugging information by using the topic of the websocket_message instead of the payload data. This would cause some messages to appear empty when they were not.
Added a wait state for re-connecting to the web socket server for system status service so it would not exit immediately when the websocket server exited.
Added more PHPDoc Block information.
