µTorrent consumes all the system memory.

I'd been using 2GB of memory (temporarily I'm using 1GB because I sent 1GB for repairing) I don't remember when it started but µTorrent started to consume all the system momory. I set the speed guide for 50Mbp/s and I'm using Windows Vista. I've reinstalled Windows Vista and I've upgraded µTorrent to the current version, but this phenomenon didn't disappear.

http://typingcat.googlepages.com/Clipbo … 1-full.jpg

On the taskmanager, µTorrent is using only about 50MBs of memory, but the memory usage drops significantly when I closed µTorrent, so I'm sure µTorrent is causing the memory exhaustion.

How can I fix this problem?

Re: µTorrent consumes all the system memory.

First of all, why on earth did you use 50Mbit from the speed guide? What upload speed does your ISP give you? Use that number. And I don't see it using all memory.
What antivirus and firewall (or other security software) are you running?

Re: µTorrent consumes all the system memory.

Current version as in 1.7? Get Process Explorer from sysinternals.com, run it, File > Save, then post the contents of the saved process list in the .txt file here.

Re: µTorrent consumes all the system memory.

This is a known problem with utorrent and Vista (vista x64 for me). Many users have been reporting it here, on the bugs section, and also on other forums. All over.

The utorrent developers don't want to do anything about it; they say it's a bug in the windows vista cache handling system.

Here is a thread I have opened about this a couple months ago, with replies from some of the developers (I had first supposed the bug was triggered only when burning dvds, but later found out that it can happen anytime for no apparent reason):

http://forum.utorrent.com/viewtopic.php?id=22579

To fix this problem I am now using some other torrent applications like bitcomet, which does not have this problem (some users are saying that it is "going around" the vista caching system to avoid the problem).

The utorrent developers don't want to do anything about this (as Firon said it's a vista problem, not utorrent), so you have 3 choices:

1. learn to live with the problem
2. or use another torrent application, like bitcomet for example.
3. go back to windows xp

Re: µTorrent consumes all the system memory.

Thank you all for answering my question.

To 5618,
I live in South Korea. Currently there are 3 types of FTTH (Fiber To The Home) service available for the public here. The Special service which provides 100Mbps (about 10MB/s) for both upload and download, the Premium service 50Mbps and the Light service 10Mbps. I'm using the Premium service, so I chose 50Mbit option at the Speed Guide. 100Mbps speed is common in Korea. I have not installed any anti-virus and even have disabled Windows Defender.

To Ultima,
I was using 1.6 but recently I've downloaded the 1.7 (build 2999) beta (or RC) version.

To MB
Your answer seems to be the closest answer. Maybe I should look for another software, but I've been using µTorrent ever since I first used bit torrent. So I'm hesitating to move on to another one. I'm going to install 2GB more RAM sooner or later, and let's see if  µTorrent could consume 4GB of memory. (The price for RAM is very cheap these days, so I could afford more than 4GB but 4GB is the maximum amount of memory my motherboard supports.)

Re: µTorrent consumes all the system memory.

Getting more RAM doesn't sound like a good solution to me, as the apparent memory leak shouldn't be there in the first place, and the memory usage might simply keep growing until it eats up the additional 2GB.

Re: µTorrent consumes all the system memory.

To be clear: we are interested in fixing the problem, we just have not managed to reproduce it. If anyone has specific steps, settings, or hints on reproducing this problem please let us know.

Also, if anyone has more information beyond the BitComet "bypassing" the cache rumor, that would be helpful as well.

Re: µTorrent consumes all the system memory.

I got just the same problem, expet I use Windows XP x64.
As I can remember it started yesterday, or was it the day before hmm...
Anyway I have't have this problem before, and I don't know why it started
(I have't done anything with my computer in a while).

The day it stated I had a shitload of programs running, and uTorrent was one of
the last programs that I was shutting down while a keept an eye on the memory.
And after I closed uTorrent it took a sec or two before a goot all my memory back,
at that moment I thought it was just a system error. The download was done anyway so I rebooted and did't think of it anymore, untill today when I thought it whould be a good idea to upgrade uTorrent to the newest build. When I was on your site I started to remember what happend, so I whent to the forum and found this thread.

Well I thought it might be a good idea to take a bunch of screens, and write a line or two to give the devs. a bit more info.

Here's a shot on the mem. usage after a few days uptime with gaming and all the shit you use the computer for.
http://img2.freeimagehosting.net/uploads/e8867d8f43.jpg

Just started uTorrent..
http://img2.freeimagehosting.net/uploads/bfc00ba664.jpg

After about one minute.
http://img2.freeimagehosting.net/uploads/4575808457.jpg

And this is after 5 mins, you can start see the free memory going down abit.
http://img2.freeimagehosting.net/uploads/f13e23d74e.jpg

After 10 mins, uTorrent is taking nearly 460MB of my RAM.
http://img2.freeimagehosting.net/uploads/5ae6c8845c.jpg

OMG HELP!!! - uTorrent have been running for 32 mins.
http://img2.freeimagehosting.net/uploads/05e9bc714d.jpg

BOOM headshot! - after 1 hour all my memory is gone...
http://img2.freeimagehosting.net/uploads/66415ed26a.jpg

And after exiting uTorrent, it's all back
http://img2.freeimagehosting.net/uploads/6993115e15.jpg

When it started I was using an older 1.7 build 18xx something i think it was,
so I downloaded the new RC2 build 2999 which was being used when the screens was taken.

And one more note for the devs. if I have some downloads running and uTorrent is eating all my RAM, if one of them become completed a big portion of memory is released.
Oh I almost forgot, it looks like it only happen with "fast" download, +800KB/sec.

I hope this helps, and you can work this out. Cus. I don't whant to change to another Torrent client..

edit:
My computers specs:
AMD 64 X2 +4400
4GB Kingston RAM
76GB WD Raptor (System disk)
250GB WD Caviar (all my shit)
200GB Maxtor (some more shit)
This computer is running Windows XP x64.

Re: µTorrent consumes all the system memory.

Your wish is my command...

The thing is, you can't see that utorrent.exe is taking up all memory. Thats why I started to close all the apps that I was runing when it happend the first time

But anyway, here is a pic I just took..

Re: µTorrent consumes all the system memory.

Here it is, when I saved the log I had about 1.3GB free mem left.
So utorrent took about 2GB...

Re: µTorrent consumes all the system memory.

A 'free' page is one that contains nothing useful.  A 'cached' page is one that contains something potentially useful.  Cache pages are better than free pages.  Looks to me like XP is doing just what it's supposed to - keeping potentially useful data in memory after it has been flushed to storage, in case it's wanted again.  XP if I'm not mistaken only caches currently open files, so how much it can cache depends on the size of files currently open.  With µTorrent you typically work with fairly sizable files so XP will cache a lot.

The 'commit charge' is the VM pressure leveraged by currently running processes and the kernel.  It's the sum total of their allocations.  This is the place to look for leaks.

Re: µTorrent consumes all the system memory.

Here is my experience with this problem.

I started off with Windows XP and never had a problem. I recently upgraded to Windows Vista Ultimate 32 bit edition.

While using uTorrent one night, I noticed my memory usage was sky high, higher than I've ever seen it. This was out of the blue, and nothing but uTorrent was running. I restarted the computer and my memory was back down to normal. I started uTorrent and everything appeared normal. An hour or so later, I check in and my memory usage is back to 80 or 90%. So I start looking in the process manager, and I see nothing out of the ordinary. Nothing seems to be using that much memory. So I start experimenting. The first thing I did was close uTorrent. A few seconds later, my memory usage is back to the normal 20-30%. I start up uTorrent and watch it for a little while, after about 45 minutes of running normally, my memory usage shoots up for an unknown reason. This result has been consistent in all my observations thus far.

I have been dealing with this issue by just closing uTorrent, and restarting it anytime I need to use my computer for something.

Re: µTorrent consumes all the system memory.

This is a known problem with the Windows Disk Cache. uTorrent 1.8 will have options to bypass this cache. Alphas for 1.8 are available now.
