Hello Roland,

For the file maximum number of files you have to modify the limits.conf. The settings should look like:

@<solr user> hard nofile 65535

@<solr user> soft nofile 65535

Thank you,

Dear SOLR users,

I use Solr 9.0, with open jdk 11. After installation, I managed to access
the admin page of the solr, but I always get two warnings at the startup of
the server.

One is complaining about low entropy and the other is the max number of
open files.

Is there a blog post or any guidance how to get rid of this warning message
on Ubuntu 22.04?

Thanks,
Roland
