How to setup ulimit with CF template?

[mikhail]

Hi all,
I used CloudFormation template that you provide to setup neo4j standalone enterprise 3.5.3 in my AWS account (http://neo4j-cloudformation.s3.amazonaws.com/neo4j-community-standalone-stack-3.5.3.json). Btw thank you very much for it!

Can you help me to modify it in right way to setup opened files limit? Currently I get a warning:

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

Thank you!

Ooops, this is something we should update in our CF templates and cloud images. I'll open an internal issue to try and get this addressed.

In terms of how to do this on your instance, just modify the startup scripts that the database nodes use, and follow the advice here:

Neo4j Graph Database Platform

Number of open files - Neo4j Graph Database Platform

Linux platforms impose an upper limit on the number of concurrent files a user may have open. This number is reported for the current user and session with the ulimit -n command: user@localhost:~$ ulimit -n 1024 Neo4j will also report…...

Can you ping here when you fix this issue with cloud images and CF templates?

Thank you.
