Der Heap läuft über. Entweder du brauchst den Speicher wirklich, oder du gehst zu sorglos mit deinen Objekten um.

was heisst das ich zu sorglos mit meinen Objecten umgehe?

Vielen Dank,

Soll heißen das du eventuell zu viele Objekte erzeugst, oder zu viele Daten im Speicher vorhälst oder ungünstig mit Arrays oder Strings umgehst. Ohne Kenntnis deines Quellcodes kann ich dazu nichts sagen. Profiler sollen aber nützlich sein :wink:
