qbittorrent-nox become unresponsive after a random amount of time

I have qbittorrent-nox in a docker container, it works fine until it stops responding web UI request at port 8080 after around 20 minutes to 1 hour. At startup it works completely normally, however when it become unresponsive, any web request to it will seems to never time out but stuck there(longest I've tried is stuck trying to open the web UI for 24 minutes with cURL), even with cURL.

It stops processing RSS after it become unresponsive as well.

When it stop responding, the log just ends there. Like there is no issue whatsoever. Like the time has just frozen for that process. There are no error or warning message of any kind in the log.

Version 5.1.2

What could be the issue here?
