Question

I installed Neo4j on Ubuntu 12.04 using these instructions: http://www.neo4j.org/download/linux

wget -O - http://debian.neo4j.org/neotechnology.gpg.key | apt         


        

Answer 1

You need to add the following entries into the /etc/security/limits.conf file

root   soft    nofile  40000
root   hard    nofile  40000

You need to start the service as root or using sudo

When you do that, the user that ends up starting the service is the root user.

If you dont have an entry in the file for the root user, then it would not work.

So, you just need to add those entries in the file and then reboot your server.

I had the same problem and that is how I was able to resolve it.
