Beginne bei LastFlushTimeManager.getFlushedTime (Zeile 237) und verfolge den Insert-Pfad durch VirtualStorageGroupProcessor, StorageEngine und die im Stack Trace genannten Cluster-Applier-Klassen. Vergleiche die Heap-Fehler in Cluster-RPC-, WAL-, Heartbeat- und Timed-Query-Threads, um eine reproduzierbare Ursache festzustellen. Als abgeschlossen gilt die Aufgabe, wenn die Quelle des Heap-Wachstums identifiziert und eine Korrektur mit einem Regressionstest oder einer dokumentierten Reproduktion validiert wurde.
