tedrock Posted February 19, 2008 Report Share Posted February 19, 2008 I finally decided to update to 1.7.7 today and every since I did my utorrent has been using 80-100% cpu. If have it running normally I can hardly do anything on my computer. If I GREATLY reduce my download speed it will stay around 50% CPU but I still can't watch a movie or anything because it will cause stuttering. The only way to get normal usage from my computer is if I pause ALL torrents or exit the program. I can't even leave 1 torrent going at 100% speed. I haven't changed a single setting since I updated and it worked fine before the update.I tried Process Explorer and the thread with the start address uTorrent.exe+0x1751b seems to be the cause.Here's a copy of the stack for that thread (TID 3816):ntkrnlpa.exe+0x69c9fhal.dll+0x22e7tcpip.sys+0x1ca2etcpip.sys!ARPRcv+0xd60ntkrnlpa.exe+0x16fe3nltdi.sys+0x916ntkrnlpa.exe+0x16fe3afd.sys+0x3492ntkrnlpa.exe+0x9d8d7ntkrnlpa.exe+0x965bantkrnlpa.exe+0x65a28ntdll.dll!KiFastSystemCallRetWS2_32.dll!WSARecv+0x61uTorrent.exe+0x16186uTorrent.exe+0x1692auTorrent.exe+0x17526kernel32.dll!GetModuleFileNameA+0x1b4 Link to comment Share on other sites More sharing options...
jewelisheaven Posted February 19, 2008 Report Share Posted February 19, 2008 Stack traces don't help I've tried to get stuff fixed that way and it's a no go.Are you seeing "disk overload" in the lower left part of the status bar? Link to comment Share on other sites More sharing options...
tedrock Posted February 19, 2008 Author Report Share Posted February 19, 2008 oddly enough i resolved the issue by just restarting it appears. i hard restarted earlier but maybe it's a randomly occurring or gradually over time issue. i'll wait and see.

jewelisheaven Posted February 19, 2008 Report Share Posted February 19, 2008 Could it be you were "checking" status on the previously active torrents??Checking occurs when you re-path torrents (stop right click advanced set download location) Link to comment Share on other sites More sharing options...
tedrock Posted February 19, 2008 Author Report Share Posted February 19, 2008 my torrents always go to the same location. i don't move them until they are finished seeding. if i need them somewhere else i copy them and then delete them after they are done seeding. nothing is checking when the issue occurs.UPDATE:It appears the issue does return over time. After a few hours utorrent starts eating up all my cpu. The only way I have found to temporarily fix it is by restarting. If exit utorrent it's process will remain for up to 2 minutes and will spike HUGE on the cpu basically locking my mouse up even and then finally goes away. As soon as I relaunch utorrent it very quickly goes back up to 100% cpu usage. If i log out and log back in and launch utorrent it does the same thing. I have to restart to make the issue go away for a few hours. Link to comment Share on other sites More sharing options...
Switeck Posted February 20, 2008 Report Share Posted February 20, 2008 tedrock,That sounds like a bad software firewall (got Zone Alarm?) leaking resources and driving up cpu use....Or bad drivers. Link to comment Share on other sites More sharing options...
Firon Posted February 20, 2008 Report Share Posted February 20, 2008 Can you post a HijackThis log too?Also, can you make sure that your drive controller is set to UDMA for all drives? Link to comment Share on other sites More sharing options...
tedrock Posted February 20, 2008 Author Report Share Posted February 20, 2008 UMDA is on for all drives.i believe it was my net.max_halfopen setting. i reset it 8 and have not had the problem all day. i assumed i was patched because the tweak site i was looking at mentioned a windows update that basically patched the system for you. i patched my system and set it back to 50 and just waiting to see what happens. i still don't think this is it because the settings i'm using worked for several days. the issue started right after i updated.I don't use software firewalls. And what device's drivers are you thinking are bad? Link to comment Share on other sites More sharing options...
Switeck Posted February 20, 2008 Report Share Posted February 20, 2008 Your networking card's drivers might be bad.But the half open limit being reset by a Microsoft update is the most likely explanation. Link to comment Share on other sites More sharing options...
tedrock Posted February 20, 2008 Author Report Share Posted February 20, 2008 patching it didn't resolve. i let it run all night and woke up to my system almost unusable due to utorrent using 100% cpu. but i was able to pause them all this time and get it going.i guess i'll have to get this hijacker program next.

tedrock Posted February 23, 2008 Author Report Share Posted February 23, 2008 it appears i fixed my problem by setting max half open back to the default (8)i don't know why this would be a problem since i patched my system Link to comment Share on other sites More sharing options...
Homeless Posted February 24, 2008 Report Share Posted February 24, 2008 mine is set to the default 8 and yet i still have that problemdunno if this helps but i have an app called vista manger which has the option to patch tcpip to 99999 Link to comment Share on other sites More sharing options...
intudi Posted February 28, 2008 Report Share Posted February 28, 2008 Hello.I have the exact same problem. After downloading some hours, the CPU usage increases extremely, and I can no longer exit uTorrent, it gets stuck in the task manager, or sometimes it just won't exit.Can somebody help me? How do I update my drivers? And which drivers?How do I "make sure that your drive controller is set to UDMA for all drives?"And I use Zone Alarm Free and Avira Antivirus.Any solutions?

Ultima Posted February 28, 2008 Report Share Posted February 28, 2008 Start > Run > devmgmt.mscLook at the primary and secondary IDE ATA/ATAPI controllers' properties to see if any of the connected devices' current transfer mode are PIO.While you're at it...a) get HijackThis from trendsecure.com, run it, view the log, and post the contents here get Process Explorer from sysinternals.com, run it, Ctrl+D (to show the lower DLL pane), select the µTorrent process from the list, Ctrl+S (and save the list somewhere you'll find easily -- like the Desktop) , then post the contents of the saved process list in the .txt file here Link to comment Share on other sites More sharing options...
Firon Posted February 28, 2008 Report Share Posted February 28, 2008 ZA free is the most likely cause for not being able to shutdown µTorrent. It is a horrific firewall (the pro version too). Try Comodo instead. Link to comment Share on other sites More sharing options...
intudi Posted February 28, 2008 Report Share Posted February 28, 2008 Thx for det quick replies. Before I start, I want to tell, that my uTorrent isn't using so much CPU at this moment. It starts doing that after a couple of hours, so I don't know how it effects the logs from Hijackthis etc.And by the way, I've just uninstalled ZoneAlarm. Don't know the effects of this either.I looked at devmgmtand I don't know if I've read it correctly, but it says at the 2 IDE ATA/ATAPI controllers I've got:"Activate DMA" is checked on bothand "Ultra DMA 5" Link to comment Share on other sites More sharing options...
DreadWingKnight Posted February 28, 2008 Report Share Posted February 28, 2008 CryptoAPI.dll CryptoAPI HiTRUST 2.02.0000.0034keyManager.dll keyManager HiTRSUT 2.02.0000.0018ShowErrMsg.dll ShowErrMsg 2.05.3024.0022sysenv.dll System share library HiTRUST 2.05.3021.0108SysHook.dll SysHook DLL 0.09.0007.0003I don't know what these are doing being hooked into uTorrent's process, but they are extremely suspect for doing so.

Firon Posted February 28, 2008 Report Share Posted February 28, 2008 "Ultra DMA5" is the current transfer mode? Link to comment Share on other sites More sharing options...
intudi Posted February 29, 2008 Report Share Posted February 29, 2008 I think current transfer mode is Ultra DMA 5, cause my Vista isn't in English, and the nearest I could find said Ultra DMA 5. Actually it says (translated:) "current condition" -> "ultra dma 5".I have uninstalled Zone Alarm, and temporarily there seems to be no problems, even though I haven't tried to exit uTorrent. Let's see how it will get tomorrow. What alternative firewall do you reccomend me? I have Vista. Link to comment Share on other sites More sharing options...
Ultima Posted February 29, 2008 Report Share Posted February 29, 2008 I believe Comodo has Vista compatibility, and it's a decent firewall. Link to comment Share on other sites More sharing options...
intudi Posted February 29, 2008 Report Share Posted February 29, 2008 Okay thank you very much Ultima. I'll try it.By the way, after uninstalling Zone Alarm, I don't have any CPU troubles with my uTorrent. So I think you should add ZoneAlarm to the list of apps, thay may disturb uTorrent.EDIT: I meant, after UNinstalling ZoneAlarm.. Sorry. Link to comment Share on other sites More sharing options...
Ultima Posted March 1, 2008 Report Share Posted March 1, 2008 Worth trying. If it continues to be a problem, ditch the firewall -- it's not worth the trouble. Link to comment Share on other sites More sharing options...
Firon Posted March 1, 2008 Report Share Posted March 1, 2008 You're the first person I've heard having -this- sort of issue with Zone Alarm... How weird. Link to comment Share on other sites More sharing options...
