Currently ulimit -n shows 10000. I want to increase it to 40000. I've edited "/etc/sysctl.conf" and put fs.file-max=40000. I've also edited /etc/security/limits.conf and updated hard and soft values. But still ulimit shows 10000. After making all these changes I rebooted my laptop. I've access to root password.
usr_name@usr_name-lap:/etc$ /sbin/sysctl fs.file-max
fs.file-max = 500000
Added following lines in /etc/security/limits.conf -
* soft nofile 40000
* hard nofile 40000
I also added following line in /etc/pam.d/su-
session required pam_limits.so
I've tried every possible way as given on other forums, but I can reach up to a maximum limit of 10000, not beyond that. What can be the issue?
I'm making this change because neo4j throws maximum open file limits reached error.
I am using Debian but this solution should work fine with Ubuntu.
You have to add a line in the neo4j-service script.
Here is what I have done :
nano /etc/init.d/neo4j-service
Add « ulimit –n 40000 » just before the start-stop-daemon line in the do_start section
Note that I am using version 2.0 Enterprise edition. Hope this will help you.
