A websocket will receive data as fast as it can, and store the data in a deque. If that data is not consumed as fast as it is written, then that deque will grow in size indefinitely, ultimately leading to a memory error and killing the process. Fix is to use a Queue. Read and get messages from the queue on the client side.
