Commencez par LastFlushTimeManager.getFlushedTime (ligne 237) et suivez le chemin d’insertion à travers VirtualStorageGroupProcessor, StorageEngine et les classes cluster applier nommées dans la stack trace. Comparez les échecs du heap entre les threads cluster RPC, WAL, heartbeat et timed-query afin d’établir une cause reproductible. La tâche est terminée lorsque la source de la croissance du heap est identifiée et qu’un correctif est validé avec un test de régression ou une reproduction documentée.
