CPU Usage at 100% No firewall or other sofware conflicts


Recommended Posts

For some reason, yesterday, utorrent stopped opening from taskbar. I didn't install any new programs or do anything unusual.

Checked Task Manager, showed CPU usage at 100% from utorrent.exe. Checked the FAQ, seems some firewalls do this, but I have no software firewall installed.

I DL'd and ran process explorer. Under the threads tab it shows TID 4052 is using all the CPU. All the threads showing are:





All are related to utorrent.exe from what I can see.

DPCs in main screen shows 0% CPU usage for DPCs.

Any idea what could be causing this? I tried spyware scans with updated def's (Ad-Aware, Spybot, AVG) and all they found were a few tracking cookies. No change once they were removed.

I even went so far as to try azureus, which I normally don't use, and it worked fine.

I would love to get this fixed. Is there anything else I can check?

Is this what you're looking for? I got it from the Threads tab. This is from the TID that is causing the CPU to be at 100%.

I've killed and restarted utorrent.exe many times now. No effect. Goes right back to 100% as soon as it restarts. I have done a few system restarts as well.

I closed AVG after the scan, I'm just using the free version. I have no exceptions set.

Tried that. Restarted utorrent.exe. Right back to 100% CPU again.

It seems to drop back down for about 30 seconds while the program checks to see if .torrent files are associated. I can view the program while the confirmation window is up. Once I click No (to associate the files), it hammers my CPU again and the program locks up.

You can cause uTorrent to crash and generate a dump file. That will let me inspect what it was doing at the time of the crash.

Go to the Logger tab, open the right-click menu and hold Control while selecting "Dump Memory Info". Find the resulting dump file it creates (probably in C:\Program Files\uTorrent) and post it on http://www.mediafire.com

Can't get it to crash. I can't even get it to open. I can see the system tray icon, but it doesn't open when I click it. Can't right click, either.

Although, the status bar comes up when I hover over it, and it shows the 2 torrents I had active when it started acting this way.

Didn't realize there was a beta available. I DL and tried it. Seems to be working. I'll post again if I have any new problems.

Thanks to all who posted on this thread. The support I received for this issue was impressive to say the least.

uTorrent is by far the best program out there for bittorrent. Keep up the great work.
