Hi Peterson, I ran into the same issue as you did i.e. "Caused by: java.lang.IllegalStateException: Cannot close the PageCache while files are still mapped"
I asked a question here in the group but no one answered yet. In case you manage to find a solution for your problem, can you please let me know? These kind of crashes and lack of support from neo4j staff makes me think, I should walk away from Neo4j and revisit it at a later time. Thanks in advance!
