But I'd like to hear from the experts what they say about it. How can we handle these warnings? Sometimes our clients receive warnings like this: WARNING org.jboss.remoting.transport.bisocket.BisocketServerInvoker$ControlMonitorTimerTask@1f175da: detected failure on control connection Thread[control: Socket[addr=XXX/yyyy,port=7063,localport=4328],3,main] (a2sc3v-fo68je-gdiugvr5-1-gdjopipw-llpl: requesting new control connection (org.jboss.remoting.transport.bisocket.BisocketServerInvoker) which we consider to be a part of the warnings the server logs. Can that be? Or is it another phenomenon? I can't find any informations about these questions. The ones I see are out of date (three years ago)... Anyone who can help me?
