The remote endpoint was in state [TEXT_FULL_WRITING] which is an invalid state for called method

[psarin]

Getting the above error after lucee websockets has been running for a while and/or a large number of messages are passed through. The closest thing I could find is the following, where they recommend using wsSession.getAsyncRemote().sendObject(message) rather than wsSession.getBasicRemote().sendObject(message)
