Switeck Posted August 17, 2008 Report Share Posted August 17, 2008 It's probably bad settings you're using.Please tell us what settings you're using and speed of your connection.If that's not the problem, knowing this will help us decide what to try next.

al007 Posted August 17, 2008 Author Report Share Posted August 17, 2008 Connection Type: xx/1Mbit in Speed Guide. I have qualitative symmetrical 1Mbit connection.There is no problem with uTorrent 1.7.7 with the same settings files. Link to comment Share on other sites More sharing options...

DreadWingKnight Posted August 17, 2008 Report Share Posted August 17, 2008 That doesn't necessarily prove a bug.Post a hijackthis log and try net.max_halfopen lower than 8 (you CAN go as low as 1) Link to comment Share on other sites More sharing options...
al007 Posted August 17, 2008 Author Report Share Posted August 17, 2008 When do you want me to make this log: when it happens that uTorrent cant connect to tracker, or any time?I'll try lower net.max_halfopen, but it takes time.Please take into consideration, that uTorrent cant connect only to tracker, downloading and uploading works normal with usual speed.

Switeck Posted August 17, 2008 Report Share Posted August 17, 2008 It's hard to say a lot more without knowing more about your computer and network.1st link in my signature has steps to try and lists information we'll need (such as HijackThis! log) if things don't work.

Firon Posted August 17, 2008 Report Share Posted August 17, 2008 When it's unable to connect to anything (even local proxies), please do this.ntsd.exe -p 4100 -e 4100 -c ".dump /mf c:\jit.dmp;q" where 4100 is the PID, and c:\jit.dmp is the resulting dump file.Upload the dump file to mediafire.com.

magila Posted August 18, 2008 Report Share Posted August 18, 2008 FWIW, I'm having the same problem and the inability to connect appears to extend to ALL types of connections. Trackers, peers, RSS feeds, check for updates, in none of these cases can utorrent establish an outgoing connection. Incoming peer connections and DHT still work though.

Greg Hazel Posted August 18, 2008 Report Share Posted August 18, 2008 What if you stop all torrents, turn off the DHT, and wait about 10-15 minutes? Does starting one torrent after that work?Also, what network card and driver version are you using? Link to comment Share on other sites More sharing options...

Greg Hazel Posted August 19, 2008 Report Share Posted August 19, 2008 I did encounter the same behaviour on my own system, with a different network card. The odd thing is that TCPView reports around 10 connections that uTorrent is unaware of, all in SYN_SENT and not progressing. This really looks like a bug in the Windows TCP stack.Do you see any Event ID 4226 entries in the Event Viewer? Link to comment Share on other sites More sharing options...
al007 Posted August 19, 2008 Author Report Share Posted August 19, 2008 Yes, but the last one was 2 days ago. And this screenshot I've made today. Link to comment Share on other sites More sharing options...
yyzgayguy Posted August 20, 2008 Report Share Posted August 20, 2008 I'm having precisely the same problem. I had perfect stable behaviour with the previous version for many months. From Day One of install 1.18 I find the client performs OK for a few hours, thereafter showing red arrows and indicating "Offline (timeout)" for trackers. Not all trackers, not all of the time. If I close the client for a while and start it, it will behave normally for hours, before exhibiting this problem.I have no firewall software, no tcp/ip v6, Symantec Endpoint Anti-Virus v11, XP Pro SP3.All problems began with install of new version of uTorrent. No Other Changes Have Been Made To PC. Link to comment Share on other sites More sharing options...
Firon Posted August 20, 2008 Report Share Posted August 20, 2008 Can you try lowering net.max_halfopen to less than 8? Link to comment Share on other sites More sharing options...
Greg Hazel Posted August 20, 2008 Report Share Posted August 20, 2008 I just tried raising my half-open limit far beyond 10. I did not get an Event ID 4226, but the same symptoms did occur - "offline (timed out)" on all connections.Looking at TCPView, I see the same stack of half-open connections. But, if I waited long enough it did eventually go down! This is consistant with my understanding of how a process is penalized for busting the half-open limit. Connections are put in a queue and it drains at one connection per second.So, as Firon said, try lowering your net.max_halfopen to something like 3, and see if the problem ever happens again.

al007 Posted August 20, 2008 Author Report Share Posted August 20, 2008 So why uTorrent 1.7.7 doesn't have such problem? Link to comment Share on other sites More sharing options...
Greg Hazel Posted August 20, 2008 Report Share Posted August 20, 2008 I'm not sure yet. If we can determine whether lowering the halfopen limit helps or not, I'll be closer to narrowing it down. Link to comment Share on other sites More sharing options...
magila Posted August 21, 2008 Report Share Posted August 21, 2008 I've been running for a couple of days with the half-open limit set to 5 and no problems. Link to comment Share on other sites More sharing options...
al007 Posted August 21, 2008 Author Report Share Posted August 21, 2008 net.max_halfopen = 5. A day of continuous work. No problems so far. Link to comment Share on other sites More sharing options...
