Same here! Never had this before...

[Tydus]

Same here from a Deluge user (Server: 2.1.1, libtorrent: 2.0.7.0). Happens especially frequently if the torrent contains many small files. I think it should be a problem in libtorrent (maybe some race condition among AIO threads?)

[giesmininkas]

Sounds like the same issue I have: https://github.com/arvidn/libtorrent/issues/7137

[giesmininkas]

Could someone test same qBittorrent version with two build variants: libtorrent v2.0.7 and v2.0.6? As mentioned in https://github.com/arvidn/libtorrent/issues/7137, I'm only able to reproduce the issue with v2.0.7.

[Seeker2]

Strangely, I'm seeing a similar error message as well, even though I'm using uTorrent...but only to uTP-using libtorrent seeds or peers: [qBittorrent/4.4.4.0 (0.0)]: Disconnect: Peer error: The system cannot find the file specified.

More details: https://github.com/arvidn/libtorrent/issues/3542#issuecomment-961017235

currently fixed on the RC_2_0 branch so in the next version 2.0.8
