We have a problem where we create a GPRS connection that is then kept alive for days. This GPRS connection is used for a socket connection and for sending http posts. Socket connection is sending keep-alive message between predefined periods. E.g. in Finland our system is working quite nicely and we are hitting timed out http posts only from time to time. However in Australia we have big problems. Loads of HTTP post are timed out and no response is received. Also Socket connection is reporting similar problems. Has anyone met similar problems?
