            <title>[SERVER-43215] Have a better way to enforce internal threads that acquire strong locks are killed during step up/down</title>
                <link>https://jira.mongodb.org/browse/SERVER-43215</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Currently, internal operations rely on calling&#160;&lt;tt&gt;setSystemOperationKillable()&lt;/tt&gt; to &lt;a href=&quot;https://github.com/mongodb/mongo/blob/78bd6e0f1860a7c9a7ea8aa0f5de5cfb7c40465f/src/mongo/db/repl/replication_coordinator_impl.cpp#L1858&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;allow themselves to be killed&lt;/a&gt; by the RstlKillOpThread on step up/down. This design is error-prone and has resulted in bugs like &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-40594&quot; title=&quot;Range deleter in prepare conflict retry loop blocks step down&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-40594&quot;&gt;&lt;del&gt;SERVER-40594&lt;/del&gt;&lt;/a&gt; and &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-43174&quot; title=&quot;Designate the MigrationDestinationManager&amp;#39;s migrateThread as system operation killable&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-43174&quot;&gt;&lt;del&gt;SERVER-43174&lt;/del&gt;&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;Instead, we should somehow make the RstlKillOpThread more intelligent on what operations to kill without relying on clients setting the flag. I think we should always kill operations that have intention to acquire strong locks (Mode X/S) because they could be blocked on prepared transactions while holding onto RSTL, preventing step up/down from proceeding.&lt;/p&gt;</description>
