+ | === Limit Warnings === | ||
+ | |||
+ | Starting with Solr 7.3.1, you may see warnings on startup resembling: | ||
+ | |||
+ | < | ||
+ | *** [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 | ||

+ | </ | ||
+ | |||
+ | This is warning of some default settings that could impact the performance of your Solr instance. They are unlikely to cause problems if you are only using Solr for testing/ | ||
+ | |||
+ | The best way to address the errors on Linux platforms using systemd is to start Solr through systemd and ensure that your [[# | ||
