Updated to 1.9 alpha 14659 as the dev's asked in 1.8.3 thread. It works good for 2 hours already with bt.transp_disposition=255, no weight gaining spotted uT now: Private Bytes ~ 80Mb's, Working Set ~ 55Mb's, Virtual Size ~ 261 in proc. exp. I have ~500 torrents active now, bt.allow_same_ip=true, bt.multiscrape=false, bt.scrape_stopped=true(our local torrent won't support scrape, so i am too ), that's all i think. Had a leak in 1.8.3 but this one seems fine to me. Except the download shown around ~14kbyte\s when i'm only uploading, not downloading anything.
