Good day.

 

After few days of usage found memory leak

 

OS Windows 8.1 (x64) with all current updates

utorrent 3.4.2 build 38397 (32 bits)

ISP - MKSBalashihi (MTS Rus)

Firewall+Antivirus - Kaspersky Internet Security (KIS) 15.0.2.361

 

32 Gb of RAM leak out during 8 hrs. Long time before did not use torrent, so cant say it was not happened with previous versions. Current memry leak was confirmed during 4 last days.

a few days ago i also started getting 95% memory usage (out of 6GB RAM) while uTorrent is minimized (only happens when PC goes idle like watching movies (nevermind, it happens as long as utorrent is running, idle, gaming etc)), and it drops to ~25% after i close utorrent

i dont remember ever having this problem

did multiple searches with Malwarebytes Anti Malware and Bitdefender Internet Security, quick scans, full scans, nothing found

 

uTorrent 3.4.2 (build 38913) [32-bit] on Windows 7 Professional

 

edit: installed an older version of uTorrent (2.2.1 Build 25154) and got rid of the "fishy" hidden large amount of RAM that uTorrent uses

anon, your uTorrent is only using about 100mbytes of RAM TOTAL

The problem is the windows disk cache subsystem.

yes, i can read that, and i cant explain what else is using so much memory, but the point is it only happens while uTorrent is running.

 

went to device manager - disk drivers - properties - policies - disabled Enable write caching on the device and rebooted pc.

as long as utorrent is running, physical memory usage slowly builds up to 95%+, 5 seconds after i close utorrent, it goes back to 30-60% whatever apps im using.

I'm having memory leak problems as well, although not sure if it's actually a memory leak or just caching on HDD. Sometimes Process Hacker 2 shows uTorrent using a lot of RAM, sometimes it doesn't show (although uTorrent still causing about 20-25% RAM usage). Will try 3 methods and report here: 1. Running as admin. 2. Setting uTorrent.exe priority to below Normal, 3. Setting uTorrent.exe I/O priority to low.

 

Edit: 1. After one night of seeding 14 torrents (about 4GB total) Process Hacker 2 showed uTorrent using only 78MB of RAM, but after exiting uTorrent it showed 30% more RAM available.  

2. After another 10 hours of seeding the same number of torrents with "low priority" on uTorrent.exe the amount of ram that was used was about 20%. A bit lower. Although I was actively using my PC during that time.
