 Note:  If you previously rebooted your system without manually stopping Solr, the script may mistakenly believe that it is still running.  In this case, a [[starting_and_stopping_solr#restarting_solr_manually|manual restart]] should solve the problem. Note:  If you previously rebooted your system without manually stopping Solr, the script may mistakenly believe that it is still running.  In this case, a [[starting_and_stopping_solr#restarting_solr_manually|manual restart]] should solve the problem.
  
 +=== Limit Warnings ===
 +
 +Starting with Solr 7.3.1, you may see warnings on startup resembling:
 +
 +<code>
 +*** [WARN] *** Your open file limit is currently 1024.
 + It should be set to 65000 to avoid operational disruption.
 + If you no longer wish to see this warning, set SOLR_ULIMIT_CHECKS to false in your profile or solr.in.sh
 +*** [WARN] ***  Your Max Processes Limit is currently 15058.
 + It should be set to 65000 to avoid operational disruption.
 + If you no longer wish to see this warning, set SOLR_ULIMIT_CHECKS to false in your profile or solr.in.sh
 +</code>
 +
 +This is warning of some default settings that could impact the performance of your Solr instance. On most Linux platforms, this can be addressed by editing the /etc/security/limits.conf file and adding these lines:
 +
 +<code>
 +username         soft    nproc           65000
 +username         soft    nofile          65000
 +username         hard    nproc           65000
 +username         hard    nofile          65000
 +</code>
 +
 +(where "username" is the name of the user that will be running Solr).
 +
 +It may be necessary to log out of your terminal session and log back in for these settings to take effect.
