antisolar Posted January 28, 2007 Report Share Posted January 28, 2007 Using version 1.6 (build 474) under WinXP SP2, even though max half open connections are set to 6 in Preferences > Advanced, µT frequently breaks the limit and cripples my connection. (I don't have a patched tcpip.sys and I don't want to patch it)At the moment netstat gives me:TCP 10.0.0.3:2769 xxx.xxx.xx.xxx:13903 SYN_SENT 228 [utorrent.exe]TCP 10.0.0.3:2770 xx.xxx.xx.xx:58215 SYN_SENT 228 [utorrent.exe]TCP 10.0.0.3:2771 xx.xx.xxx.xxx:62050 SYN_SENT 228 [utorrent.exe]TCP 10.0.0.3:2772 xx.xxx.xxx.xx:55166 SYN_SENT 228 [utorrent.exe]TCP 10.0.0.3:2773 xx.xxx.x.xx:22024 SYN_SENT 228 [utorrent.exe]TCP 10.0.0.3:2774 xx.xxx.xxx.xx:55043 SYN_SENT 228 [utorrent.exe]TCP 10.0.0.3:2775 xxx.xxx.x.xx:6881 SYN_SENT 228 [utorrent.exe]TCP 10.0.0.3:2776 xxx.xxx.xx.xxx:23763 SYN_SENT 228 [utorrent.exe]TCP 10.0.0.3:2777 xxx.xx.xxx.x:6881 SYN_SENT 228 [utorrent.exe]TCP 10.0.0.3:2778 xx.xxx.xxx.xx:55000 SYN_SENT 228 [utorrent.exe]Is there another setting that controls this?Edit: It seems these connections are "stuck" as they are not closed even when I stop the (only) torrent (unlike the incoming connections which are closed).

Ultima Posted January 28, 2007 Report Share Posted January 28, 2007 Hm. My guess is that it's a bug of some sort. µTorrent shouldn't be doing that, but many people have reported issues with using 8 for net.max_halfopen (with unpatched TCPIP.sys) while leaving the max halfopen connections setting at 8 worked just fine in Azureus...

Switeck Posted January 29, 2007 Report Share Posted January 29, 2007 TCP View is here:http://www.microsoft.com/technet/sysinternals/ProcessesAndThreads/ProcessExplorer.mspxTCP View allows you to close/end ip-to-ip connetions...and on Win XP shows what programs are making the connections in the first place.Even if it is a bug, you can close the "stuck" SYN_SENT ip-to-ip links and possibly avoid the problem for longer.

antisolar Posted January 29, 2007 Author Report Share Posted January 29, 2007 Closing the stuck half open connections with TCPView makes µT open more and more connections which -I think- eventually knocks out my DSL router for a while. :/ Link to comment Share on other sites More sharing options...
