@Uj947nXmRqV2nRaWshKtHzTvckUUpD Any actual crash report? or did it crash to desktop? Any qbittorrent.dmp files in %LOCALAPPDATA%\CrashDumps? Anything related to qbittorrent in eventvwr logs?

i didn't see any crash in that folder, nor any event. Today i ran again out of space, but this time the client didn't crash. But instead the torrent was put in upload mode. Don't know how to replicate exactly.

later edit: I tried replicating, by downloading a torrent larger than space left and this time qbittorrent crashed. As previously said, there's no crashdump or event. Opening the client again while no space on device will put the torrent in error state with error message: <Errored: Couldn't write to file. Reason: "There is not enough space on the disk". Torrent is now in "upload only" mode.> Afterwards i made space again, and tried replicating again third times, but the client didn't crash anymore, but instead torrent errored.

It would be most helpful & highly appreciated if you could try to produce a valid stack trace from instructions/method in https://github.com/qbittorrent/qBittorrent/issues/20869#issuecomment-2168749126

I was able to re-test today on: Qt: 6.4.3 Libtorrent: 2.0.11.0 Boost: 1.86.0 OpenSSL: 1.1.1w zlib: 1.3.1

The client didn't crash anymore, and instead logged this error: - File error alert. Torrent: "<torrent_name>". File: "<PATH>". Reason: "<torrent_name> file_write (<PATH>) error: There is not enough space on the disk"

the torrent status changed to 'upload only' mode.

Thanks to all developers and everyone involved.
