            <title>[DOCS-6885] Add &quot;Locked Memory Pages&quot; ulimit note</title>
                <link>https://jira.mongodb.org/browse/DOCS-6885</link>
                <project id="10380" key="DOCS">Documentation</project>
                    <description>&lt;p&gt;MonogoDB Enterprise that the ulimit for &quot;Locked Memory Pages&quot;  is at least 16 VM pages. This means we want 64kb on Linux x86, and 1024 kb on Linux POWER. Linux x86 defaults to 64kb so this should not be an issue.&lt;/p&gt;

&lt;p&gt;This applies to MongoDB 3.2 Enterprise and later for x86. For Power, it will be 3.3.0 and later. &lt;/p&gt;</description>

                            <comment id="1228514" author="kevin.pulo@10gen.com" created="Thu, 7 Apr 2016 02:03:29 +0000"  >&lt;p&gt;&lt;del&gt;In addition, in my testing I found that in Ubuntu 12.04 and 14.04:&lt;/del&gt;&lt;/p&gt;
&lt;ul&gt;
	&lt;li&gt;&lt;del&gt;Adding a line such as &quot;&lt;tt&gt;limit memlock 128 128&lt;/tt&gt;&quot; to &lt;tt&gt;/etc/init/mongod.conf&lt;/tt&gt; did not increase the amount of locked memory as I expected.&lt;/del&gt;&lt;/li&gt;
	&lt;li&gt;&lt;del&gt;Adding a line &quot;&lt;tt&gt;limit -l 128&lt;/tt&gt;&quot; immediately prior to the &quot;&lt;tt&gt;exec start-stop-daemon ...&lt;/tt&gt;&quot; line in that file &lt;b&gt;also&lt;/b&gt; did not increase the mongod&apos;s memlock ulimit as I expected it to.&lt;/del&gt;&lt;/li&gt;
	&lt;li&gt;&lt;del&gt;Increasing the &lt;tt&gt;memlock&lt;/tt&gt; ulimit for the &lt;tt&gt;mongodb&lt;/tt&gt; user in &lt;tt&gt;/etc/security/limits.conf&lt;/tt&gt; also did not succeed.&lt;/del&gt;&lt;/li&gt;
	&lt;li&gt;&lt;del&gt;However, bizarrely, adding &quot;&lt;tt&gt;limit -l 128&lt;/tt&gt;&quot; to &lt;tt&gt;/etc/default/mongod&lt;/tt&gt;&quot; (which is sourced by &lt;tt&gt;/etc/init/mongod.conf&lt;/tt&gt;) &lt;b&gt;did&lt;/b&gt; cause the mongod memlock ulimit to be adjusted.&lt;/del&gt;&lt;/li&gt;
	&lt;li&gt;&lt;b&gt;EDIT:&lt;/b&gt; I got bitten by &lt;a href=&quot;http://askubuntu.com/a/238069&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;this stupidity in upstart&lt;/a&gt;.  If I do &quot;&lt;tt&gt;stop mongod&lt;/tt&gt;&quot; and &quot;&lt;tt&gt;start mongod&lt;/tt&gt;&quot;, then it picks up the adjusted &quot;&lt;tt&gt;limit memlock&lt;/tt&gt;&quot; line as it should.&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;Se still likely need to investigate the most appropriate way of adjusting the memlock ulimit for each Linux distribution.&lt;/p&gt;</comment>
                            <comment id="1228512" author="kevin.pulo@10gen.com" created="Thu, 7 Apr 2016 01:59:23 +0000"  >&lt;p&gt;Although the &lt;em&gt;minimum&lt;/em&gt; recommendation for the memlock ulimit should be 16 VM pages, and 3.2.5+ will issue a startupWarning if started with less than that, currently the Encryption At Rest feature requires 16kb + 4kb * number_of_dbs.  &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-23570&quot; title=&quot;Make SecureAllocator a real allocator&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-23570&quot;&gt;&lt;del&gt;SERVER-23570&lt;/del&gt;&lt;/a&gt; should lower this requirement considerably.&lt;/p&gt;</comment>
