@fluidvoice commented on GitHub (Jan 10, 2019):

I'm on Manjaro Linux (also Arch based), Qbittorrent v4.1.5 also.
It's crashing all the time randomly. The app just disappears. What's also really annoying is that after it crashes when restarted the previously in-progress downloads restart - revert back to zero bytes downloaded. I have over 2GB free RAM, so it's not low-memory related. I had only 4 torrents active, 3 paused and only 1 downloading. It has crashed at least 3 times like this in the past hour.
Edit: I just removed all paused torrents so only one is downloading and it finally completed without crashing.
