Subject [jira] [Commented] (SOLR-9560) Solr should check max open files and other ulimits and refuse to start if they are set too low
Date Fri, 01 Dec 2017 20:52:00 GMT

    [ https://issues.apache.org/jira/browse/SOLR-9560?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16274958#comment-16274958

Erick Erickson commented on SOLR-9560:
--------------------------------------

[~shalinmangar] Hmm, on a quick search I don't see a good way to get the ulimit information
in Java. So are you suggesting that the script do the ulimit (or whatever) and pass the variables
to the Java executable?

If that's the case, I don't see how that would work with an API. What am I missing here?
