I am having a weird issue with qbittorrent on Raspberry Pi 4. Whenever I try to download a torrent which is very large In size, qbittorrent will keep crashing and on restarting, it will do recheck and start torrent and then again crash. I usually get these large sized torrents from private tracker. Recent one was 187GB in size.
But instead if I have smaller torrents like 40-60GB ones, they don't crash qbittorent.
Never really tried with sizes like this but it seems like the CPU horsepower and/or qbt might be the issue.
Can you try with transmission/rtorrent?
If you want to debug qbt then here's another option-
Open /home/qbittorrent/.config/qBittorrent/qBittorrent.conf
Add these lines to enable logging.
[Application]
FileLogger\Enabled=true
FileLogger\Age=6
FileLogger\DeleteOld=true
FileLogger\Backup=true
FileLogger\AgeType=0
FileLogger\Path=path/to/log/folder/of/your/choice
FileLogger\MaxSize=10
Explanation:
FileLogger\Backup= backup the log file when it becomes bigger than FileLogger\MaxSize= x MB
FileLogger\DeleteOld= delete the backup logs after FileLogger\Age= 6 FileLogger\AgeType= x where x can be 0=days, 1=months, 2=years
Now after qbt crashes go to the log path and check the file for issues.
