Calibre's user-interface (UI) freezes periodically. I also run the web server.

What log(s) can I view to figure out why the UI freezes?

I have to send "SIGKILL" to the 3 Calibre processes:

Code:

44636 ?        Ssl    0:18 /opt/calibre/bin/calibre --detach
44639 ?        S      0:00 /opt/calibre/bin/calibre-parallel --pipe-worker from calibre.utils.safe_atexit import main; main()
44718 ?        S      0:00 /opt/calibre/bin/calibre-parallel --pipe-worker from calibre.utils.ipc.pool import run_main, worker_main; run_main(61, worker_main)

and restart calibre every-time the UI freezes.
