These segments in the cache will be released to > `MemoryManager` after some specify operations such as join operator finishes > to build data in `LazyMemorySegmentPool.cleanCache` method. But these > segments are still in `LazyMemorySegmentPool.cachePages`, it may cause memory > fault if the `MemoryManager` has deallocated these segments -- This message was sent by Atlassian Jira (v8.20.1#820001)
