snowdecoy Posted August 31, 2008 Report Share Posted August 31, 2008 Hi. I recently updated to 1.8. After a period of 7-10 hours since utorrent starts, all four different trackers of my seeding torrents go offline and never come back unless I close and restart utorrent.After restarting the program everything works just fine and trackers keep updating normally for the next 7 hours or so, until at some point all go offline again.I never had any problems with the previous version (I can't remember which one exactly, but it was the latest). I'm using kerio software firewall and avast pro antivirus. I have forwarded the port for incoming connections (port:53322) in my rooter even though the rooter firewall is disabled.I haven't changed anything in my configuration except for the update in 1.8 so I can't think of anything to try since everything was working properly before.Any help would be appreciated ...Thanks in advance.

DreadWingKnight Posted August 31, 2008 Report Share Posted August 31, 2008 Have you tried setting net.max_halfopen lower than 8? Link to comment Share on other sites More sharing options...
snowdecoy Posted August 31, 2008 Author Report Share Posted August 31, 2008 Haven't tried it. I don't have the slightest idea what it is or where to find it or even what it does.Any links would be useful.Thanks for the quick answer though friend.

DreadWingKnight Posted August 31, 2008 Report Share Posted August 31, 2008 Preferences - advanced.Turning it down to 4 turns down the rate at which new connections are attempted, giving your system more breathing room. Link to comment Share on other sites More sharing options...
snowdecoy Posted August 31, 2008 Author Report Share Posted August 31, 2008 ok thanks for the info. I'll give it a try even though a downgrade to the previous 1.7.7 (finally found it in my hard drive) sounds more appealing.Do you know if the setting has been changed in 1.8 different than in previous versions?As I first wrote what troubles me is that I didn't have this problem before the update, so I'm looking for that detail that changed and is causing this ...

Firon Posted August 31, 2008 Report Share Posted August 31, 2008 You can try the 1.8.1 beta. Link to comment Share on other sites More sharing options...
snowdecoy Posted September 1, 2008 Author Report Share Posted September 1, 2008 I tried it but unfortunately is banned in the main tracker I use.Why they banned it, is beyond me, since 1.8 is not banned. :/1.7.7 is online for almost 20 hours now and everything works properly again :/ Link to comment Share on other sites More sharing options...
Switeck Posted September 1, 2008 Report Share Posted September 1, 2008 Betas are typically banned until someone determines they're stable/safe. Link to comment Share on other sites More sharing options...
TraderJones Posted September 2, 2008 Report Share Posted September 2, 2008 Just an FYI, I've encountered two other users of 1.8 with the identical problem. Changing the half-open helped one, but not the other. Link to comment Share on other sites More sharing options...
HiGhLaNdR Posted September 2, 2008 Report Share Posted September 2, 2008 I have the exact same problem. Changed to 4 and waiting for results. So far so good. 1h passed. Link to comment Share on other sites More sharing options...
moabboy Posted September 3, 2008 Report Share Posted September 3, 2008 I too have the same problem after upgrading to 1.8. Hopefully the fix helps as I rely heavily on the RSS downloader and this problem affects the RSS feeds as well Link to comment Share on other sites More sharing options...
AnacortesBoys Posted September 3, 2008 Report Share Posted September 3, 2008 WinXP Pro SP3uTorrent 1.8, fresh install (all default settings)I can verify that I have encountered the same issue when upgrading to 1.8 with default Advanced uTorrent settings. I also noticed though that all network related functions of the PC seemed sluggish when the uTorrent timeout condition was occurring. For example, a local web and eMail server taking much longer to perform functions. Restarting uTorrent did not always fix the problem, although restarting the PC always would. I concluded it to be a deeper networking problem, and noticed I was getting more of the System Events:(Log ID 4226:TCP/IP has reached the security limit imposed on the number of concurrent TCP connect attempts.)than I would have expected, for the number of torrents I was working with, and they seemed to correspond roughly with the beginning of a timeout condition.First, upgrading the nic driver had no impact. I didn't really expect it would, but it was out of date and needed to be addressed anyway, and was relatively low risk.Second, addressed the underlying issue in the tcpip.sys driver and the half-open limit (targeting the error event), using the well-known patch from lvllord.de, accepting the default new limit of 50.I have additionally increased the uTorrent advanced setting net.max_halfopen to 20 (from 8), based on the assumption that if all 8 were being used before, more where probably needed anyway for efficient BT operations.I've been running for 2 days now with no further occurrence of any network related issues.

DreadWingKnight Posted September 3, 2008 Report Share Posted September 3, 2008 I have additionally increased the uTorrent advanced setting net.max_halfopen to 20 (from 8), based on the assumption that if all 8 were being used before, more where probably needed anyway for efficient BT operations.This is an incorrect assumption.BitTorrent applications do NOT need an increased limit. An increase halfopen limit is COMPLETELY useless after the first minute of a torrent's activity. Link to comment Share on other sites More sharing options...
Switeck Posted September 3, 2008 Report Share Posted September 3, 2008 If uTorrent gets a green light, it needs fewer half open connections to start-up quickly.8 is enough. Link to comment Share on other sites More sharing options...
Ultima Posted September 4, 2008 Report Share Posted September 4, 2008 More than enough, really. If other applications create more than 2 half-open connections while µTorrent is using the full 8 (assuming TCPIP.sys is unpatched), overloading will ensue. BitTorrent clients are probably more connection-creation heavy than many of the usual/casual Internet-enabled applications too, so allowing it such a large portion of the already small half-open connection limit is really overkill.
