Weird CPU problem

M4NIC · April 23, 2009

Hello guys, long time μtorrent user, first time bug reporter :/

Ive been using μtorrent for a long time, and never had any problems with it. Lately however, I encounter an annoyance which I think is indirectly related to it.

Whenever I leave a torrent to download overnight, the next day the computer is sluggish, audio randomly stutters, and even something as simple as opening a website causes massive CPU spikes. This weirdly enough continues even when I close μtorrent, and doesnt stop even with logging off. When I restart everything is ok.

The reason Im associating this with μtorrent (I can hear the cries of "youve got a virus", "spyware", "your pc is crap" etc coming ;o) is that this only happens after Ive left the pc overnight, downloading a torrent (Note: I only d/l one torrent at a time for multiple connections theorists, and that is with μtorrent's default settings of 50 per torrent and 200 g-max). If I leave it doing nothing or downloading other stuff everything is allright the next morning (or afternoon )

I can be downloading/seeding a torrent for hours while working on the pc, and nothing like this happens. It only does it when I leave it overnight.

My setup is as follows:

hardware: Toshiba Satellite pro U200, Intel Core 2 Duo 1.8GHZ, 2GB RAM, μtorrent is on the primary disk but the torrents download to a USB external 500GB disk.

software: Windows Vista SP1 (:shivers:), μtorrent 1.8.2, NOD32 v2.70.39, Comodo firewall

Sorry if ive bored you but this is getting extremely annoying, especially the sound stutter problem.

Cheers

I'm experiencing somewhat of the same, but it doesn't happen all the time, it can go about a week or so between each time.

My symptoms are exactly the same as yours : "Whenever I leave a torrent to download overnight, the next day the computer is sluggish, audio randomly stutters, and even something as simple as opening a website causes massive CPU spikes. This weirdly enough continues even when I close μtorrent, and doesnt stop even with logging off. When I restart everything is ok."

My specs.

Core 2 Quad Q9650, 8GB DDR2-1066, Vista 64 Ultimate w/SP1, μtorrent 1.8.2, Symantec Antivirus 10.2.1,

Comodo Firewall 3.8 64-bit.

Computer usage. Running Boinc/WCG 24/7, several files active in uTorrent all the time. Torrents go to an internal 750GB SATA-drive.

When I first encountered this problem, I suspected Boinc, but alas - that was not the case.

And the only known cure that works is a reboot.

I can see that we both run Vista, and Comodo.

I suspect that Comodo is in fact the culprit here, or maybe some malfunction between Vista/Comodo/uTorrent.

I earlier ran XP with more or less exact same software, main difference was that Comodo was the 32-bit version instead of 64, and then I didn't have problems like this.

So you might want to try another firewall and see if that changes things.

I myself haven't been bothered enough yet by it to check it out myself.

Let me know how it works out for you, if this is something you might try out :-)

M4NIC · April 23, 2009

hey fellow stutterer ;p

Im glad to see that Im not the only one.. the thing is, Ive always had this config (μtorrent, COMODO) with no problems whatsoever.

I really like COMODO, and I really cant be bothered to change firewall (too much config :/) so what will probably happen in my case is try another torrent software :/

As I forgot to mention, Im running COMODO v. 3.8.65951 and 32-bit Vista.

MetaBaron · April 23, 2009

Yeah, I dread changing firewall, for the same reasons as you. But I also like uTorrent (used Azureus earlier, until the bloat infestation) - so I myself will probably just resign myself to rebooting once in a while, as it seems that I'm not as afflicted as you.

This is a really strange error, because according to Task Manager, nothing seems to be wrong, but the sluggishness and cpuspikes are undeniably there.

Next time it happens I'll have to see if I'm up for an extended session of troubleshooting

M4NIC · April 23, 2009

Its really annoying... the other weird thing is that I never experience stuttering and slugginess, even when doing x.264 encoding and a host of other stuff, where the CPU is constantly at 99-100%. I only get it when the CPU spikes to 100% after a night of μtorrent..

MetaBaron · April 23, 2009

I have Process Explorer good to go for troubleshooting when this problem resurfaces, I believe it will make it easier to pinpoint the exact cause of the sluggishness. You might want to check it out, if you haven't already :-)

got it already but thanks... nothing seems out of the ordinary when I check it when the problem occurs :/

Post Hijackthis and Process Explorer logs when uT is running.

Guide: http://forum.utorrent.com/viewtopic.php?id=29748

Dont forget to select utorrenT.exe and enable DLL mode (ctrl+d) in PE.

Very useful to show what process is injected into uT.

here they are.. when the problem occurs Ill do it again so we can see any differences...

All of these are potential problems.

moogly · April 24, 2009

I think guard32.dll is Comodo.

Anyway IMON 2.7 has been the source of issues with uT (cf sticky on boards).

M4NIC · April 24, 2009

I noticed that the new version of IMON in V.3 of NOD is problematic, but mine is 2.70.39. Anw I already have put μtorrent in the list of exceptions but with no difference.

moogly · April 24, 2009

And did you try to uninstall it (temporarily) and see if the issue continues?

M4NIC · April 24, 2009

uninstall what? μtorrent, COMODO or NOD32?

DreadWingKnight · April 24, 2009

comodo or nod32

M4NIC · April 26, 2009

well nod32 is gone, replaced with avg but to no change.

the weird thing is now it does it a bit while actually downloading torrents, not only after a night of downloading.

DreadWingKnight · April 26, 2009

And what about with rocketdock uninstalled?

M4NIC · April 26, 2009

rocket dock is the least suspect as its the same version since the day I installed it, where the whole setup had none of these problems. The only things routinely updated where NOD, COMODO and utorrent.

DreadWingKnight · April 26, 2009

That doesn't answer my question.

jewelisheaven · April 26, 2009

"Sluggish" on Vista doesn't mean much, TBH... Procexp is most often used to check specific thread or process CPU % usage for the bottleneck/problem.

In any case, even though the problem likely isn't uT, if you can provide more information while it's happening anyone here will have the skills to help you. A tip: Open the process in procexp by double-click, jump to the threads tab, it will show you the DLL which is causing the trouble in realtime.

P.S. It was nice of MS to give Sysinternals' tools short URLs ... I mean they're pushing "live" right?? For future reference, you can access most/all *I haven't found one which didn't work* of them in this format http://live.sysinternals.com/tools/

I.E. http://live.sysinternals.com/tools/procexp.exe is for Process Explorer

eMWu · May 19, 2009

I can confirm 100% that it's a problem between Comodo and uTorrent.

I've been having the same issue - sound stuttering after leaving comp with utorrent over night.

So last night I decided to test it and uninstalled Comodo... and voila, the problem's gone.

I'm running Windows 7 RC x64, so the bug is not limited to Vista.

The software versions I've been using:

COMODO Internet Security 3.9.95478.509

uTorrent 1.8.2 (build 14458)

Now I'm off to Comodo forums to see if it's a known issue.

EDIT: It's a bug in Comodo, its users keep reporting it here. Apparently version 3.5 isn't affected, only the newer ones are.

M4NIC · May 19, 2009

Hmmm interesting...

the thing is, I dont think its limited to utorrent + Comodo. To verify if its only utorrent related, I installed Deluge and used it for a while, and the problem was still there, interestingly enough with slightly different symptoms.

The stuttering with Deluge appeared in shorter bursts, and it would occasionally appear after a relatively short period of time (eg not only overnight).

This is really starting to piss me off as Ive been using uTorrent and Comodo for years now and no such problem ever happened to me before.. I guess Ill just move the torrents on to my new system and not install Comodo on it..

***EDIT****

Well I can confirm that Comodo v.3.5.57173.439 works perfectly fine, been running it for two days now and no stuttering whatsoever.
