NUC mit ioBroker und Historian auf einer lokalen MySQL

Ich hatte nun 3x hintereinander, dass grob nach 3 Tagen meine MySQL im Hintergrund von ioBroker "grundlos" nicht mehr da war. Das hab ich dann nur zufällig gemerkt, weil in der Vis eine LogAnzeige steht...

Nun habe ich mal ins MySQL-Log geschaut und staune nicht schlecht (log unten)

1. Als Warnung für Euch ... falls auf einmal keine historischen Daten gelogged werden...
2. Wie behebe ich das? Die Doku sagt mir nichts und wenn ich google komme ich zum droppen von irgendwelchen internen Tabels ... da hab ich etwas bedenken :-(

Eure Meinung?

Gruss -
