How to fix "Cannot close the PageCache while files are still mapped"

Incorrect file permissions on store files

It is common to start the database as different users, this can leave store files owned by other user ids. ( e.g. root )

In such case, you might want to fix the store files and directory. For example : ${NEO4J_HOME}/data/databases/graph.db/

  • From Neo4j version 3.5, you should be able to recover by clearing up some space and restarting the affected node.
