Since then, utorrent (which I was using at the time) started to act weird. For example, after adding a few large torrents (usually over 10 GB in size) and starting to download, the client uses HDD continously and doesn't download. First I thought it's all about preallocating space, but it sits still even after 24h and after HDD stops churning.\r\n\r\nI moved to Qbittorrent and it was better, but a couple days ago I added some really large torrents (8 of them, around 80 GB each - it's a TV series that I already own in Bluray format but I want to stream it to my mobile devices using PLEX media Server). Qbittorrent started behaving exactly like uTorrent.\r\n\r\nWhat happens:\r\n\r\n1. Qbittorrent attempts to download;\r\n2. Download works for a few seconds (up to 30 seconds) at Ok speeds (even up to 20 MBps)\r\n3. Download speed goes gradually down to zero;\r\n4. HDD light is always ON;\r\n5. Qbittorrent shows all torrents as \"Stalled\";\r\n6. Closing Qbittorrent leaves \"qbittorrent.exe\" process alive in processes list;\r\n7. trying to end process yields no results, I have to restart the OS to get it out of the way.\r\n8. If I don't restart and try to open Qbittorrent again, it starts and creates another process in the process list which actually can be killed.\r\n\r\nMy guess is that Qbittorrent tries to preallocate files (although I told it not to) OR it has issues trying to download at high speeds and somehow craps out. I have gone as low as allowing only 2 torrents to download at the same time, which maked Qbittorrent set all but 2 torrents as \"Queued\" but the two remaining ones are... yes, you guessed right: \"Stalled\".\r\n\r\nSame behavior is visible for 3.1.2 and 3.1.4.\r\n\r\nSmaller torrents (e.g. DVD-sized) work fine. usually I am getting single-torrent download speed of 60-70 MBps, which probably is capped by HDD transfer capabilities."},"comment":{"url":"https://api.github.com/repos/qbittorrent/qBittorrent/issues/comments/94677387","html_url":"https://github.com/qbittorrent/qBittorrent/issues/1220#issuecomment-94677387","issue_url":"https://api.github.com/repos/qbittorrent/qBittorrent/issues/1220","id":94677387,"user":{"login":"nomadturk","id":10355660,"avatar_url":"https://avatars.githubusercontent.com/u/10355660?v=3","gravatar_id":"","url":"https://api.github.com/users/nomadturk","html_url":"https://github.com/nomadturk","followers_url":"https://api.github.com/users/nomadturk/followers","following_url":"https://api.github.com/users/nomadturk/following{/other_user}","gists_url":"https://api.github.com/users/nomadturk/gists{/gist_id}","starred_url":"https://api.github.com/users/nomadturk/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/nomadturk/subscriptions","organizations_url":"https://api.github.com/users/nomadturk/orgs","repos_url":"https://api.github.com/users/nomadturk/repos","events_url":"https://api.github.com/users/nomadturk/events{/privacy}","received_events_url":"https://api.github.com/users/nomadturk/received_events","type":"User","site_admin":false},"created_at":"2015-04-21T07:48:21Z","updated_at":"2015-04-21T07:48:21Z","body":"It stalls...\r\nStill does.\r\nIt seems random. I tried it on different connections. With or without disk allocation and upnp. They didn't affect nothing.\r\n\r\nRight now, I don't know if it's a coincidence or not but when I disabled Anonymous mode and  Local Peer Discovery my stalled torrents started to run again. But on the other hand, before disabling these, I have added other torrents from various trackers, some worked some stalled...\r\n"}}
