Few nights ago in build 18786 I increased my disk cache to a ridiculous size, 4GB (this crashed it but i expected that) 2GB, than 1 than 512mb before turning it back to automatic management. Since then I seemed to have a memory leak that has not been fixed by upgrading to the RC. The end result is all my system ram is chewed up. However system process monitor doesn't show utorrent using it all. However when i quit out of utorrent it frees it all back up usually 2 GB or so. I was wondering if anyone else has experienced this. First time reporting a bug so sorry if I'm doing it wrong or being vague. Operating system is windows 7 64 bit.
