Neo4j 2.2.1 server not starting after db creation via java code

Starts with a new graph.db folder. I am using inline db, java and cypher graph to create nodes. It seems that these nodes have been successfully created. Debugging and checking the result object.

I want to run neo4j server to check nodes in browser. However, it gives the message:

bash -4.2 $. / neo4j-community-2.2.1 / bin / neo4j start

WARNING : Max. 1024 open files allowed, 40,000 minimum recommended. See Neo4j manual. Starting Neo4j Server ...

WARNING : without changing user process [2868] ... waiting for server to be ready ... Failed to start 120 seconds. The Neo4j server may not be running, check the logs.

I have checked console.log and message.log. But there is no mistake. I don't know what to read in the log files to put here for diagnostics. Please advice.

console.log:

Where else to look for errors? How can I get the neo4j server?

Edit:

Log message checked. The text is below. It looks like it turns off via code:
