Hello, When launching solr (Ubuntu 16.04) I'm getting: * [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
This appears to be related to a known bug in Ubuntu<https://issues.apache.org/jira/browse/SOLR-13063> https://blog.jayway.com/2012/02/11/how-to-really-fix-the-too-many-open-files-problem-for-tomcat-in-ubuntu/ I was wondering if you have some workaround. I followed the solutions in the following threads: https://vufind.org/jira/browse/VUFIND-1290 https://underyx.me/2015/05/18/raising-the-maximum-number-of-file-descriptors and was able to resolve Max Processes Limit but not File limit: * [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 Waiting up to 180 seconds to see Solr running on port 8983 [] Started Solr server on port 8983 (pid=2843). Happy searching! cd proc# cat 2843/limits: Max processes 65000 65000 processes Max open files 4096 4096 files The problem persisted after upgrade to Ubuntu 18.10 Any other solution would be appreciated. Otherwise can you please tell me what are the likely consequences of the open file limit? ********************************************************************** The information in this email is confidential and may be legally privileged.
