I always thought it was related to the PLC hanging up without following the correct procedure for doing that. Sort of like just hanging up the phone without saying goodbye. Perhaps really implementing an exception handler and just swallowing the exception Because we know we're operating in "unpolite" environments ... but not sure what We could do to gracefully handle the situation. @Julian ... would it be ok to catch that and simply log an "INFO" severity message ("Remote hung up unexpectedly") Chris Am 12.04.19, 13:52 schrieb "Otto Fowler" <ottobackwa...@gmail.com>: The netty handlers don’t implement exceptionCaught so the default is to spew to logs. I don’t speak german so I don’t know what the exception message is. Maybe the handlers should implement the method.
