Re: [Neo4j] Database locked problem

[Michael Hunger]

This rather looks like a permission problem. Can you check that the user that runs neo4j has r/w access to /home/keen/lbs_graph_tourist and the directories and files below.

And at least has a +x on the directories above.

Hi,

I have some problems when starting the server, I guess due to some locking mechanism. However I check that no process is using the database.

Below is my log:
