In the logs you’re showing, Gladys restarts approximately every 20 seconds. Have you tried looking at htop for at least 1 minute, just to see if it’s not the RAM usage that gradually increases until the crash, and so on?
To check if it’s really an issue with Gladys 4.72 (or if it’s unrelated), you can try running the container of the previous version:
gladysassistant/gladys:v4.71.0
