I installed the latest Solr on the lates Ubuntu OS by the production script
based on the documentation. I did not customized anything during the
installation process. I managed to create a core.
Anytime I try to restart Solr (which runs as a background service), I got
the following error:
*sudo -su solr /opt/solr/bin/solr restart*
[sudo] password for roland:

If you no longer wish to see this warning, set SOLR_ULIMIT_CHECKS to false

My questions:
1. Why Solr looks for start.ini file in the directory the *sudo -su solr
/opt/solr/bin/solr restart *was executed and how can I solve it?
2. The max processes and and max files generated a warning. I put two lines
into /etc/security/limits.conf:
solr soft nofile 65000
solr soft nproc 65000
But still as you see the file related issue was solved but process related
issue was not.How an I fix it?
Thanks,
Roland
