Ngone51 commented on issue #23497: [SPARK-26578][CORE] Synchronize putBytes's memory allocation and putting block on memoryManager URL: https://github.com/apache/spark/pull/23497#issuecomment-457444659 > I just think there's some inconsistency here : we evicted all entries but still got smaller free space than pool size. In your test, no blocks in entries when task 2 try to evict blocks, right ? So, how can we say *we evicted all entries but still got smaller free space* ? From my view, task 2 does not evict any blocks, so it can not accquire enough free memory.
