ssan998 Posted March 12, 2009 Report Share Posted March 12, 2009 我是中国用户，是中国网通光纤，我的操作系统是windows2008 Sever Datacenter ,我用的下载版本是:uTorrent V1.8.3Beta出现错误，用最新版本µTorrent V1.9 alpha 14659也是，都出现这样的错误：如果图不能看，请点http://imggz.jpg.name/hrwwjrtsrwydthhdswtyjswrswddrjhrztth.jpg状态：错误：数据错误（循环冗余检查），然后就停止下载，再点启动，一会也是这样的提示。用µTorrent 1.9 alpha 14659下载时，速度很慢，旦用µTorrent 1.8.3BETA下载时，速度很快很快。think ssan998 is trying say that he is a china user, he's using China Netcom fiber optic.when using 1.8.3 beta and alpha 14659 also having this same error message "Status: Error: Data error (cyclic redundancy checking)"when this error appear, it stop downloading. awhile after clicking manual start also appear the same thingwhen using alpha 14659, speed very slow but when using 1.8.3 beta speed very fast.

DreadWingKnight Posted March 12, 2009 Report Share Posted March 12, 2009 Well that data error indicates a failing hard drive or hard drive controller. Link to comment Share on other sites More sharing options...
zhong881209 Posted March 12, 2009 Report Share Posted March 12, 2009 lol, translate to chinese is harder then to english.数据错误表是一个衰退/失败的硬盘或硬盘控制器will force recheck helped? Link to comment Share on other sites More sharing options...
DreadWingKnight Posted March 12, 2009 Report Share Posted March 12, 2009 Nope. If the hard drive is failing, it must be repaired or replaced before ANYTHING is done on it in uTorrent. Link to comment Share on other sites More sharing options...
Illusion4u Posted March 12, 2009 Report Share Posted March 12, 2009 Neronut just like me @ #701http://forum.utorrent.com/viewtopic.php?pid=397218#p397218 Link to comment Share on other sites More sharing options...
Neronut Posted March 13, 2009 Report Share Posted March 13, 2009 Hi Illusion4u, did you ever figure out why? I have started using my server for running µTorrent now because of this but its W2k3 so its suffers from the pre-Vista network stack. Link to comment Share on other sites More sharing options...
Illusion4u Posted March 13, 2009 Report Share Posted March 13, 2009 No Neronut, since that version it simply does that.I tried disable encryption and do some other changes, but still the same. Link to comment Share on other sites More sharing options...
Switeck Posted March 14, 2009 Report Share Posted March 14, 2009 If the high CPU usage is possibly due to bad implementation of the TCP/IP stack under Vista/W2k3/W7, then try disabling uTP, DHT, UPnP, etc...and see if that helps. Link to comment Share on other sites More sharing options...
rafi Posted March 14, 2009 Report Share Posted March 14, 2009 and just to be sure - disable TCP as well... Link to comment Share on other sites More sharing options...
Switeck Posted March 14, 2009 Report Share Posted March 14, 2009 Rafi, if you're making fun of my suggested testing proceedures...it's not helpful for who I'm trying to help.You can also try disabling uTP connections...and with difficulty Teredo as well (if you've previously enabled it).

rafi Posted March 14, 2009 Report Share Posted March 14, 2009 sorry about that, but this was not my intention. I was just kidding... but then I thought, maybe eliminating ALL communication to peers (also responses to incomings) can help too. Anyways, I think people mentioned correlation of CPU consumption to bad interaction with external applications (firewall/NOD32, av, etc)edit:the idea was to use bit mask such as 128 so to have all TCP+uTP bit set to 0...

Illusion4u Posted March 15, 2009 Report Share Posted March 15, 2009 With 2 - outgoing uTP - Problem 8 - incoming uTP - Not even one conection255 - both TCP and uTP, incoming + outgoing - Problem 15 - both TCP and uTP, incoming + outgoing - Problem 1 - outgoing TCP - No problem 4 - incoming TCP - No problemKIS is configurated like this Link to comment Share on other sites More sharing options...
imperia Posted March 15, 2009 Report Share Posted March 15, 2009 I got very low upload speed with version 1.9 and version 1.8.3. With version 1.8.2 my upload rate is like 5-10 times faster. I lost some ratio at torrent sites. But now! Downgrade to 1.8.2.Are there some settings I am missing? Link to comment Share on other sites More sharing options...
Firon Posted March 15, 2009 Author Report Share Posted March 15, 2009 Illusion4u, and with KIS uninstalled? Link to comment Share on other sites More sharing options...
Illusion4u Posted March 16, 2009 Report Share Posted March 16, 2009 The same, the high cpu usage it's from utorrent. Link to comment Share on other sites More sharing options...
rafi Posted March 16, 2009 Report Share Posted March 16, 2009 Illusion4u , and if you set bt.transp_disposition to 128 (disabling all...) ? Link to comment Share on other sites More sharing options...
Neronut Posted March 16, 2009 Report Share Posted March 16, 2009 I primarily use uTP as it helps with speeds. From Illusion4u's results it seems it is the issue?I use Windows Firewall and have a corporate version of Symantic Anti-Virus. When I get home today I will try and see what happens when I disable them. Although my problem is seemingly intermittent so I will see what happens.On a side note: I have noticed since the last build and the newest built that the UPnP is having trouble mapping TCP and/or UDP ports. It will give an error saying it could map the ports or it will sometimes say that there was a bad command and the ports weren't mapped. Although I have a feeling this is my stupid router casing this problem. Its a Linksys WRT54GS v6 where the S part has never worked, even with the corresponding Linksys PCMCIA card.

dantexaiver Posted March 16, 2009 Report Share Posted March 16, 2009 is 1.9 a viable option right now to be used to torrent? or should did i stick with 1.8.2? Link to comment Share on other sites More sharing options...
Switeck Posted March 17, 2009 Report Share Posted March 17, 2009 Try v1.8.3 instead of v1.8.2 at least. Link to comment Share on other sites More sharing options...
gav616 Posted March 17, 2009 Report Share Posted March 17, 2009 thanks for all the hard work on this, its going along nicely.one pet hate that is still not fixed in the alpha is, when i untick 'ask tracker for scrape information' then when i download a torrent it still scrapes information from the servers, I initially thought that this option unticked would grey out the tracker list when adding a new torrent so it would never touch the trackers and only use PE and DHT.

kokobaroko Posted March 17, 2009 Report Share Posted March 17, 2009 HiI tested 1.9 about a month ago and upload limiter was broken. I tested newest 1.9 today and limiter is working so thats great. Sadly uTP is still not working optimally I seed about 20 torrents, upload limit set to 45KB/s.With 1.8.1 (so no uTP support) my download is a floating 3KB/s (TCP acks), upload 45-55KB/sWith 1.9 (255 set, so uTP enabled) my download is a floating 10KB/s (uTP acks take 7KB/s of my bandwidth), upload 45-50KB/sbasically uTP is stealing 7KB/s of my downstream. uTP is too chatty when it comes to acks.

Switeck Posted March 17, 2009 Report Share Posted March 17, 2009 kokobaroko,Did you have net.calc_overhead enabled under v1.8.1? Link to comment Share on other sites More sharing options...
kokobaroko Posted March 20, 2009 Report Share Posted March 20, 2009 yes, We've been over this before http://forum.utorrent.com/viewtopic.php?pid=378617#p378617Im not talking about uTorrent graphs, im talking about outside software counting actual bits and bytes (wireshark for example).Last time I only noticed broken upload limit. It was so bad I didnt bother to look at download differences between pure TCP and uTP.uTP was meant to be better. It shouldnt spam acks like crazy. Currently uTP is 300% less efficient while seeding (3 versus 10 KB/s of used downstream). Link to comment Share on other sites More sharing options...
