Wenn nach Restart so eine Meldung kommt:

# /etc/init.d/solr restart



*** [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

Sending stop command to Solr running on port 8983 ... waiting up to 180 seconds to allow Jetty process 13380 to stop gracefully.

Waiting up to 180 seconds to see Solr running on port 8983 [|]  

Started Solr server on port 8983 (pid=13709). Happy searching!

 

Die Lösung:

# pico -w /etc/security/limits.d/solr.conf

solr             soft    nofile          65000

solr             hard    nofile          65000

solr             soft    nproc           65000

solr             hard    nproc           65000

    I had this exact issue and your site was the only place I found the fix.

    It'd be nice if the module developer applied your fix though.

    Good work! Much appreciated!
