---------------------------
Summary: Open file limit warning when starting solr
Key: SOLR-13063
URL: https://issues.apache.org/jira/browse/SOLR-13063
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Components: SolrCLI
Affects Versions: 7.5
Reporter: Rony
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://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
Any other solution would be appreciated.
Otherwise can you please tell me what are the problems that I'm likely to
encounter?
