I am trying to download torrents with µTorrent on Windows Vista (I tried multiple versions, from 2.0 to 3.0) but it keeps leaking and reaches up to 500 MB on memory before being terminated.

Does anybody have this issue? Could it be because I'm downloading many files at the same time? How can I solve this problem?

EDIT: I've also noticed that it tends to get stuck while checking torrents (it has to check them after crashing). Might that be the problem?

are you sure that its not the read and write buffers using the ram. Under heavy usage utorrent will use a good bit of ram for buffers. – Lamar B Aug 10 '11 at 22:07

Oh, now it all makes sense.

It seems that one of your torrents got corrupt and that could cause a memory leak...

I'm afraid I have to say so, but you should get back-up and get rid of your current torrents and try 1-by-1.

It started all of a sudden, I didn't install anything new or controversial lately. – Gabriele Cirulli Aug 10 '11 at 22:16
@Gabriele: Updated, I believe one of your torrents is broke. – Tom Wijsman Aug 10 '11 at 22:21
Ah okay, I didn't know that could happen. I'll give that a try. – Gabriele Cirulli Aug 10 '11 at 22:23
I deleted all of my incomplete torrents and data, then restarted 2 of them. The memory still keeps going up. – Gabriele Cirulli Aug 10 '11 at 22:31
@Gabriele: Restarted as in redownloaded the .torrent? What if you download a random .torrent? – Tom Wijsman Aug 10 '11 at 22:42

I have not seen this behaviour on version 2 and never used version 3.

From what I have seen, Utorrent has always been very stable and a ultra low footprint - I recommend trying to reset any settings if you have tried to tweak them.

Alternatively, I would recommend using Utorrent 1.8.2 build number 14458. If you do not need any of the new features (which you don't if all you want to do is download Torrents), then this is by far the best build out there.

Trying that build now. I'll keep you updated. Thanks. – Gabriele Cirulli Aug 10 '11 at 22:16
