            <title>[SERVER-78632] Exception in QuerySettingsManager lock acquisition triggers server crash</title>
                <link>https://jira.mongodb.org/browse/SERVER-78632</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;&#160;&lt;a href=&quot;https://github.com/10gen/mongo/blob/08d4338485a18d17cc2615fccb52f8286ff877a3/src/mongo/db/query/query_settings_manager.cpp#L167&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;This &lt;/a&gt;lock acquisition may throw. Furthermore, this function is called from the ClusterServerParameterRefresher thread, which does not seem to catch DBExceptions. When the lock acquisition does throw, (e.g. an unfortunately timed shutdown), std::terminate() is called crashing the entire server. The only manifestation of this issue in our testing has been shutdown, but it may be possible to trip this in other ways.&lt;/p&gt;</description>

I&apos;ve tried to phrase the ticket in a way that doesn&apos;t imply one way or the other (or neither) is the correct solution.&lt;/p&gt;</comment>
