<p dir="auto">In our reference documentation, we currently specify what JVM versions are supported on the setup page:</p>
<p dir="auto"><a href="https://www.elastic.co/guide/en/elasticsearch/reference/current/setup.html" rel="nofollow">https://www.elastic.co/guide/en/elasticsearch/reference/current/setup.html</a></p>
<p dir="auto">This is just duplicating the information in our support matrix here:</p>
<p dir="auto"><a href="https://www.elastic.co/subscriptions/matrix" rel="nofollow">https://www.elastic.co/subscriptions/matrix</a></p>
<p dir="auto">Are we worried about the reference and support matrix getting out of sync?  Shouldn't we just refer users to the support matrix?</p>
<p dir="auto">In <code class="notranslate">/etc/default/elasticsearch</code> we have <code class="notranslate">MAX_OPEN_FILES=65535</code>. If you uncomment that, but don't edit it, and start ES you get this in the logs;</p>

<p dir="auto">Can we just increase the default by one to ensure our checks align with our default settings?</p>
