The problem we are facing is that the notification messages are cut of for some reason. I can sometimes see that the KeepAlive read() gets the same message ( it checks the format of the message and decides it is not a KeepAlive response message but rather a notification. So looks like KeepAlive "eats" part of the message and then notification reader is reads what is left. > > Any ideas of how to solve this without the mess of multiple thread sync? > > //mike > You can't read with multiple threads from the same InputStream. And multiple thread sync is not a mess, it's art. You need a single-threaded read + multi-threaded dispatch. -- DF.
