I've had various pains with QBittorrent (nox) which seem to vary based on the version of the client and the version of libtorrent used. Out-of-memory and resume issues, but varying according to the torrent size, number of simultaneous downloads, and version/configuration specifics. Torrent software (the clients and the libraries) feel a little out-of-sync with prevailing torrent sizes and bandwidth availability.
