2.2.0 23703 - insane lag and memory usage(GB's) while some downloading


Recommended Posts

Does it look like a small torrent client?


and after killing uTorrent and trying again it lucky got working fine.


For some downloads (rare i suppose) but this happens not the first time, the whole system starts to lag cuz of uTorrent and almost hangs (Win Xp, Intel Core 2 Duo E6600) and to save the system i have to kill uTorrent and try again every time this happens, no additional .dll's for uTorrent, no antiviruses, no viruses, clean uTorrent works bad and makes system lag to freezing.

Hope everything is seen in the screen, tell if you need more info.

Can you take a screenshot of the Speed tab? Switch it to the Disk Statistics view first.

now there are only zero's, when should i take it? before uT window freezes and stops to update visible data?

If it's something to see about caching, uTorrent caching is off and caching is fully relied on windows disk caching.

if you insist:


I'd take a dump, but I doubt it gonna be taken fine and fast for few GB's of memory with such system lag

So, if it's not uT's cache (because it's turned off) and you aren't using apps, then it's something that's hooking into uT, probably a firewall. It's hard to tell from the log, though.

Try creating a memory dump for uT before the memory usage gets too insane (<200mb).

As you could see from the above logs I have no firewalls nor any 3rd party programs that could hook into uT.

Anyway i'll try to take a dump with pmdump if I'd have a possibility to do so, hope a dump would definately help.

Problem takes place for big torrents with high download speeds (6+ MB\s) sometimes but not allways

btw, where would you prefer me to upload that huge dump?

Put it up on mediafire.com and email me the link. You can use ntsd to make dumps on XP.

In the Windows Task Manager or Process Explorer, look for the [PID] of the µTorrent process. From there, File > Run > ntsd.exe -p [PID] -e [PID] -c ".dump c:\jit.dmp;q"

where [PID] needs to be replaced with the PID of the µTorrent process found in the process list viewer (don't include square brackets). The resulting dump can be found as c:\jit.dmp. Do this when µTorrent hangs, and post the dump.

Took another one, it should work now, see mail

Hope it'd help to see where the problem is

some more details:

when i stop torrent memory starts to reduce to normal amount, after i start in some random time it expands quickly from 10mb to 1GB+ in few minutes

when i limit my speed to 1,5MB\s it works fine but when it's 6+MB\s this memory leak might appear.
