                <link>https://jira.mongodb.org/browse/SERVER-39211</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;The change to reduce tcmalloc size classes from&lt;/p&gt;

&lt;p&gt;&lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-22906&quot; title=&quot;MongoD uses excessive memory over and above the WiredTiger cache size&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-22906&quot;&gt;&lt;del&gt;SERVER-22906&lt;/del&gt;&lt;/a&gt;: Cut down number of tcmalloc size classes&lt;/p&gt;

&lt;p&gt;is no longer usable in gperftools-2.7 due to a new alignment requirement. We can rework the patch to modify the strategy to reject any merges that would violate this new alignment requirement.&lt;/p&gt;</description>
