Eventhough MSLAB is enabled, cells bigger than chunk size or > upserted/incremented/appended cells are still allocated on the JVM stack. If > such cells are found in the process of flattening into CellChunkMap > (in-memory-flush) they need to be copied into MSLAB. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
