posted November 7, 2002 3:59 AM We have a piece of code that ftps our web site changes to a 3rd party server on a daily basis. Intermitantly, the following socket exception is throughen System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host Server stack trace: at v.b(Delegate A_0, Object[] A_1) at Dart.PowerTCP.Ftp.Tcp.Receive(Byte[] buffer, Int32 offset, Int32 size, SocketFlags socketFlags) at m._j(Byte[] A_0, Int32 A_1, Int32 A_2) at Dart.PowerTCP.Ftp.SegmentedStream.Read(Byte[] buffer, Byte[] delimiter, Int32 offset, Int32 count, Boolean& found) at System.Runtime.Remoting.Messaging.StackBuilderSink.PrivateProcessMessage(MethodBase mb, Object[] args, Object server, Int32 methodPtr, Boolean fExecuteInContext, Object[]& outArgs) at System.Runtime.Remoting.Messaging.StackBuilderSink.AsyncProcessMessage(IMessage msg, IMessageSink replySink) Exception rethrown at [0]: at v.b(Delegate A_0, Object[] A_1) at Dart.PowerTCP.Ftp.Ftp.Put(String localFileName, String remoteFileName) We’ve been looking at it and unable to track down the problem; has anyone had a similar problem and come up while an answer? Or, is there a way to re-establish the socket and carry on? |

posted November 7, 2002 9:21 AM A Trace log may turn up something. Check out the Ftp.Trace topic in the docs (ms-help://PowerTCPFTP/PowerTCPFTP/Dart.PowerTCP.Ftp.Ftp.Trace.html) for instructions on creating a Trace log. Also, is the 3rd party server always online, or does it ever get shut down/rebooted? This may be the cause. You could write code to catch the socket exception, then try to resume the download. See the Ftp.Restart property (ms-help://PowerTCPFTP/PowerTCPFTP/Dart.PowerTCP.Ftp.Ftp.Restart.html) for more info. |

posted November 7, 2002 9:54 AM Thanks for those pointers. I've just spoken to the 3rd party supplier and they are now admiting that their ftp server is the problem, but the upgrade is 1-2 months away and that may slip! Thanks again. |
