Will add information if I'm able to reproduce it.

This is probably (indirectly) caused by ActivityWatch/aw-qt#49

[asukaminato0721]

I met the same problem. But this is crazy.

@wuyudi Holy moly. Sorry about that.

PRs welcome! (I'm afraid I'll keep procrastinating on this otherwise)

[ErikBjare]

The following PRs should make sure this never happens again:

• Rotating logfiles with max size: fix: added rotating logfile handler with max size to prevent large logs aw-core#114
• Handle the errors better: fix: improved error handling to avoid logspam aw-watcher-window#73

Thanks for reporting @ivanpondal & @wuyudi!
