Hello Twsocket, I use the latest ICS v7 distributive. The problem happens on [not my] WinXP system with slow DSL connection. I cannot reproduce it on other PCs, so I gave that user a special version that writes logs to file. The problem is as follows: when the file is completely uploaded to FTP server, the program sometimes "hangs" until ftp.AbortAsync is called manually. Here is the final part of the log in normal situation:
================================================ ... 15:13:38:799 DataSocketPutDataSent 32768 15:13:39:429 019559D8 TriggerDataSent 804 15:13:39:430 DataSocketPutDataSent 31535 15:13:39:912 019559D8 TriggerDataSent 804 15:13:39:912 DataSocketPutDataSent 0 15:13:39:912 019559D8 TCustomWSocket.Shutdown 1 804 15:13:40:057 ! Data Session closed 15:13:40:057 ! Next3PutAsync 15:13:40:058 019559D8 TCustomWSocket.Shutdown 1 804 15:13:40:061 >|226 Transfer complete| 15:13:40:061 ! Next3PutAsync 15:13:40:061 ! HighLevelAsync 0 15:13:40:061 ! HighLevelAsync done 15:13:40:084 019551B4 TriggerDataSent 832 15:13:40:227 >|221 Goodbye.| 15:13:40:227 019551B4 TCustomWSocket.Shutdown 1 832 ================================================ And here is the log when the hanging occurs: ================================================ ... 01:25:54:968 DataSocketPutDataSent 32768 01:25:55:765 00C45A34 TriggerDataSent 796 01:25:55:765 DataSocketPutDataSent 20016 01:25:56:281 00C45A34 TriggerDataSent 796 01:25:56:281 DataSocketPutDataSent 0 01:25:56:281 00C45A34 TCustomWSocket.Shutdown 1 796 01:25:56:453 ! Data Session closed 01:25:56:453 ! Next3PutAsync 01:25:56:453 00C45A34 TCustomWSocket.Shutdown 1 796 !!! The file is completely uploaded. Here the program hangs and the !!! user aborts the transfer: 01:30:05:062 ! Aborting 01:30:05:062 ! HighLevelAsync 0 01:30:05:062 ! Abort detected 01:30:05:062 ! HighLevelAsync done 01:30:05:093 ! Aborting ================================================ So, the difference is that on the problematic PC the line 15:13:40:061 >|226 Transfer complete| is not always received or processed properly. What is the reason and how to fix this? PS: when the user runs the same program with ICS v5 component, it works on that problematic computer ALWAYS ok, i.e. it never hangs. ================================================ -- Best regards, Antol mailto:spama...@mail.ru -- 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
