I don't think so, not realy. It would however retrieve (other) messages from the queue if any, hence give all clients a chance to do some work as well, would just lead to better load balancing. Lengthy blocking tasks should be avoided as much as possible since by default the listening socket and all clients share the same thread. >> >>> Sometimes it happens, that in the Server the OnDataAvaiable-Callback >>> stops to be triggered. >>> If i call receive(nil,0) on the affected socket, everything gets >>> back working correctly. >>> In my opinion some postmessage-calls in the socket are discarded >>> because the windows message queue for the server process is full. >>> If i set HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows >>> NT\CurrentVersion \Windows\USERPostMessageLimit to Value of 50.000 >>> Everything seems to be working fine. >> >> IMO TWSocket should be changed to raise an Exception if a call to >> PostMessage() fails, currently it doesn't check the PostMessage() >> return value. > > This would be as suitable solution, especially for environments with > more than 10.000 Client. IMO it would be just useful for debugging purposes, warning the developer that the application design should be revised. One cannot resolve this error condition without calling the message pump, which may lead to other odd behavior. -- Arno Garrels -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
