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

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

This worked for me on Arch Linux (x86_64), where prior to these modifications ulimit -n was 1024):

1. Edit /etc/pam.d/su, add:

   session required pam_limits.so

2. Edit both

   /etc/systemd/system.conf

   /etc/systemd/user.conf

   add to each (whatever value you desire: I chose 100,000):

   DefaultLimitNOFILE=100000

3. Reboot.

   $ ulimit -n 100000
