We are using neo4j neo4j-community-3.5.30. We have a java program that creates a query and inserts it using the neo4j driver session.

Since the program tries to run hundred of queries, we start getting the below error after some time.

org.neo4j.driver.v1.exceptions.ClientException: Unable to acquire connection from the pool within configured maximum time of 60000ms

Tried increasing the connection pool as well.

        Config config = Config.builder().withConnectionTimeout(30, TimeUnit.SECONDS).withMaxConnectionPoolSize(3000).withMaxConnectionLifetime(30,TimeUnit.SECONDS).withMaxTransactionRetryTime(10,TimeUnit.SECONDS)
            .build();
    driver = GraphDatabase.driver( "bolt://localhost:7687",  AuthTokens.basic( "***", "****" ),config );
