By default, Windows is limited to 10000 window handles globally. You probably hit that limit. I don't know which ICS version you are using but I suspect you are using an old one because ICS-V7 is sharing the same window (a hidden window used only for his message queue) and you can have much much more connections without tweaking Windows parameters. It is also possible that you don't free the socket after use and after sometimes you have consumed all Windows resources. Use madExcept4 and FastMM4 to help you find the leaks, if any. Please use the support mailing list to further discuss this topic. See "support" link at my website for details. -- francois.pie...@overbyte.be The author of the freeware multi-tier middleware MidWare The author of the freeware Internet Component Suite (ICS) http://www.overbyte.be -----Message d'origine----- Envoyé : vendredi 17 août 2012 16:13 Objet : CreateWindowEx failed error in TWSocket Hello Sir, I have used your ICS-ver6 ->TWSocketServer component and I am very satisfied with the performance of the socket. I use TWSocketServer component for my server application which ideally has around 1000 to 1500 Active client connections, and around 10,000 total connections in a day. I have created a .net library(dll) of your component from Delphi and using the same in c# .Net 2010. Lately i have started facing the problem of "CreateWindowEx failed". After this exception, no new connections to the server are possible. The entire machine goes into a hung state and it has to be restarted. Sample exception log is as follows for your reference. ^^-------------------------------------------------------------------^^ Source : OverByteIcs Method : AllocateHWnd Date : 2:52:43 PM Time : 8/17/2012 Computer : isp1server1 Error : CreateWindowEx failed Stack Trace : at OverbyteIcsWndControl.TIcsWndHandler.AllocateHWnd() at OverbyteIcsWndControl.TIcsWndControl.AllocateHWnd() at OverbyteIcsWSocket.TCustomWSocket.AllocateSocketHWnd() at OverbyteIcsWSocket.TCustomWSocket..ctor() at OverbyteIcsWSocket.TCustomSocksWSocket..ctor() at OverbyteIcsWSocketS.TWSocketClient..ctor() at OverbyteIcsWSocketS.TWSocketClient.@MetaTWSocketClient.@Create() at OverbyteIcsWSocketS.TCustomWSocketServer.TriggerSessionAvailable(UInt16 Error) at OverbyteIcsWSocket.TCustomWSocket.Do_FD_ACCEPT(TMessage& msg) at OverbyteIcsWSocket.TCustomWSocket.WMASyncSelect(TMessage& msg) at OverbyteIcsWSocket.TCustomWSocket.WndProc(TMessage& MsgRec) ^^-------------------------------------------------------------------^^ I have noticed that this problem occurs only on the server where no. of total connections are in the range of 9,000 to 10,000. The same server applications runs on other servers too, with an approximate load of 600-700 active connections without any problem. I would be grateful to you if you can assist me on the above mentioned problem. Thanking You in anticipation. -- 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
