Start at LastFlushTimeManager.getFlushedTime (line 237) and follow the insert path through VirtualStorageGroupProcessor, StorageEngine, and the cluster applier classes named in the stack trace. Compare the heap failures across cluster RPC, WAL, heartbeat, and timed-query threads to establish a reproducible cause. Done means identifying the source of heap growth and validating a fix with a regression test or documented reproduction.
