f your application, script or command are getting error “Too many open files” then you are hitting max open file limit allowed by Linux. You need to increase open file limit as shown below: Please open file:
Paste following text towards the end:
* hard nofile 500000 * soft nofile 500000 root hard nofile 500000 root soft nofile 500000
Once you save the file, logout, and login again.
This simple change will increase the limit on open files :)
