MySQL-Konfiguration optimieren - MySQL-Absturz und Neustart funktionieren

Mein WAMP MySQL ist in der letzten Woche 2 mal abgestürzt und ich wundere mich wirklich warum! Sobald ich den Server neu starte, funktioniert alles gut! Unten füge ich das Fehlerprotokoll von MySQL und die Datei my.ini an! Kann jemand etwas vorschlagen?

MySQL-Fehlerprotokoll:
