[PROBLEM] MoOde 7.3 unresponsive after 4-5 hours with Raspberry Pi 7" Touchscreen Display

[Sehnsucht]

Is chromium there as part of your touchscreen solution? Perhaps try a different browser? Uninstall chromium. Or try using another mpd client temporarily and see if it reoccurs. (I don't use the officlal moOde web interface at all - it's nice but i'm not interested in playlists and album art and radio stations etc, so having configured moOde using the web interface I use an android app to select music to play). Maybe stay connected to the pi via SSH whatever diagnosis you try, then run htop and see if the memory increase happens slowly over time or something triggers it. If it's chromium, kill it via htop or kill instead of rebooting - is that a 100% fix? Anything interesting in the log files in /var/log at the point you have problems?
