If that doesn’t work you might try blowing away the limits.conf file and try again.

(could have some random char there wrong that is breaking it)

logout and login again before restarting the process?

perhaps add:
session required pam_limits.so
to the file /etc/pam.d/common-session

just guesses

@Ram,

You can list all open files using the lsof command. Basically, it shows the information to look out the files that are opened by which process.

I have encountered an error in RHEL 7.8 as "Too many open files", causing an application issue. We are working side-by on the application code where there was a bug. What is that I am getting hard to check if three is a limit on the server-side configuration that a particular file can be concurrently opened for x-time, or if there is an overall max number of files that can be opened by an application/process. Where to get these configuration values? Please let me know if anyone has this information.
