jewelisheaven Posted April 19, 2008 Report Share Posted April 19, 2008 Have you gone through Ultima's extensive troubleshooting guide? http://forum.utorrent.com/viewtopic.php?id=15992 Link to comment Share on other sites More sharing options...
nivallen Posted April 19, 2008 Author Report Share Posted April 19, 2008 yeahin short, connection type - 6 Mbit ,upload 7 kB/s,no software firewall and router is linksys wrt54lg or sth with tomato firmware and no problem there... it's something with Vista SP1 or utorrent incompability with it...

jewelisheaven Posted April 19, 2008 Report Share Posted April 19, 2008 You only have 7 KiBps upload limit?! :/ I'm thinking from just that settings are defunct? What about trying turning off UPnP/NAT-PMP if it's not needed. What about DHT.... I know tomato is better than default firmware but it could be the ISP throttling or shaping when it detects any bittorrent traffic. What are your settings in the Speed Guide (Ctrl-G)?Does this happen all the time? What about with 1 torrent running? What about with only running the recent torrent from http://distribution.openoffice.org/p2p/ ? Does the interruption happen immediately after starting the torrent? And does the connectivity level out after the upload steadies at your limit? What is your Ctrl-P -> Advanced -> net.max_halfopen Link to comment Share on other sites More sharing options...
nivallen Posted April 19, 2008 Author Report Share Posted April 19, 2008 i have been using utorrent for many many months now and i have never got this problem before,so I suppose it's the Vista SP1 fault... i have 7kB/s upload limit in utorrent,because i have non symetric connection (upload is about 30 kB/s) DHT is on and so is UPnP/NAT-PMP,i haven't changed anything in utorrent and because of that i blame Vista SP1 2 other PC units are connected to this router and using utorrent with the same settings - they don't have this problem! net.max_halfopen is 8(?) ,it happens all the time now for about 2 days and,this problem don't depend of the number of torrents and happens immediately after starting the torrent! What is more - this don't depend of utorrent usage of whole bandwidth! i'm stuck with no ideas;/ Link to comment Share on other sites More sharing options...
jewelisheaven Posted April 19, 2008 Report Share Posted April 19, 2008 If you don't want to give out the logfiles best guess I can make is that http://forum.utorrent.com/search.php?action=search&forum=-1&search_in=all&sort_by=0&sort_dir=DESC&show_as=posts&keywords=vista+sp1&author=&search=Submit will help you :/ It doesn't make sense to automatically assume it's SP1 either, UNLESS your other two computers are not on Vista SP1 and don't have this problem.

PH@NT0M Posted July 22, 2008 Report Share Posted July 22, 2008 Hello, I have same problem on Windows Vista SP1, but few month I used utorrent with SP1 and all works well. When I open utorrent all browsers do not open www, but mirc, miranda, outlook still working, and when I close utorrent, only after 15-20 minutes i can open www in browsers (IE7, FF3).On russian forums about vista one man says that the problem in Windows Vista KB952709 update, and after uninstall it all works, I try uninstall it, but nothing happened.

Switeck Posted July 22, 2008 Report Share Posted July 22, 2008 Time to disable the usual suspects:DHT, LPD, UPnP, Resolve IPsSet half open max limit in uTorrent to only 1-4....and test again! Link to comment Share on other sites More sharing options...
PH@NT0M Posted July 22, 2008 Report Share Posted July 22, 2008 I have wifi router Asus WL-500W can I disable all this options? Link to comment Share on other sites More sharing options...
teemoh Posted July 22, 2008 Report Share Posted July 22, 2008 I was having this problem today after installing a old SP1 Security update. Sounds like you need to patch tcpip.sys. To confirm if you need to patch.. I recommend doing the following after a fresh boot:Open Event Viewer (http://www.computerperformance.co.uk/vista/vista_event_viewer.htm)Navigate to 'Windows Log' > 'Sytem' Load uTorrent. If you see a Warning for a tcpip then you need to patch tcpip.sysVista Autopatcher: http://www.mydigitallife.info/2008/02/17/download-vista-tcpipsys-and-uac-auto-patcher-to-increase-tcp-connection-limit/Hope this helps Link to comment Share on other sites More sharing options...
DreadWingKnight Posted July 22, 2008 Report Share Posted July 22, 2008 Patching tcpip.sys will cause more problems down the road. We recommend it only as a last resort. Link to comment Share on other sites More sharing options...
PH@NT0M Posted July 22, 2008 Report Share Posted July 22, 2008 "Set half open max limit in uTorrent to only 1-4." I set 4 (were 8) noting happened. Link to comment Share on other sites More sharing options...
hermanm Posted July 22, 2008 Report Share Posted July 22, 2008 Even WRT54GL w/ Tomato can have problems unless you are aggressive about dropping inactive TCP & UDP connections. I have mine set at 120 seconds and big global max such as 200 connections on µTorrent is working fine. Before I became aggressive about dropping those connections, the router performed poorly.

Switeck Posted July 23, 2008 Report Share Posted July 23, 2008 PH@NT0M,Are you getting event 4226 error messages in Windows Event Logger? Link to comment Share on other sites More sharing options...
PH@NT0M Posted July 23, 2008 Report Share Posted July 23, 2008 Yes, TCP/IP has reached the security limit imposed on the number of concurrent TCP connect attempts. Link to comment Share on other sites More sharing options...
Switeck Posted July 23, 2008 Report Share Posted July 23, 2008 Then uTorrent's half open limit is still set too high. Try lowering that value in uTorrent to 1 for testing. If the 4226 error messages quit appearing, then at least that's a sign we're on the right track to solving the problem.(I set my half open limit to 0 sometimes and "live off incoming connections" to keep connected peers/seeds high...to partially hide from ComCast's connection killing disruption.)

PH@NT0M Posted July 23, 2008 Report Share Posted July 23, 2008 I set net.half_open to 1 and after that there is not any 4226 errors in Event Viewer.Why all works great many months without any changes? Link to comment Share on other sites More sharing options...
Switeck Posted July 24, 2008 Report Share Posted July 24, 2008 Could be a Microsoft policy change to REDUCE Windows Vista Home Edition's max half open rate to only 2 or 4? Link to comment Share on other sites More sharing options...
Ultima Posted July 24, 2008 Report Share Posted July 24, 2008 Or it could be that he's using other applications that just happen to be constantly sucking up a bunch of half-open connection slots. AFAIK, Vista's limitation is the same as XP's across all flavors of Vista -- unlike what many people claim. Link to comment Share on other sites More sharing options...
Switeck Posted July 24, 2008 Report Share Posted July 24, 2008 Guess he needs to check out TCP View then...to find out what those other applications are, and what they're doing. Link to comment Share on other sites More sharing options...
PH@NT0M Posted July 24, 2008 Report Share Posted July 24, 2008 Hmm, I leave uTorrent working for a night and on the morning I have two 4226 errors in the log. Link to comment Share on other sites More sharing options...
Switeck Posted July 24, 2008 Report Share Posted July 24, 2008 Do you think it could be uTorrent trying to contact a LOT of torrent trackers at once? Link to comment Share on other sites More sharing options...
PH@NT0M Posted July 24, 2008 Report Share Posted July 24, 2008 I don't know =) Now I have 9 torrents from one tracker and 1 torrent from another. That's all. Link to comment Share on other sites More sharing options...
