            <title>[SERVER-35755] CollectionLock acquisition in shard_filtering_metadata_refresh.cpp can cause server to terminate on stepdown</title>
                <link>https://jira.mongodb.org/browse/SERVER-35755</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The CollectionLock acquisition in onShardVersionMismatch() can throw (for example, due to interrupt on stepdown), but it&apos;s called from the catch block in service_entry_point_common.cpp (and there is no try/catch above this point), so if it throws the exception will terminate the server.&lt;/p&gt;

&lt;p&gt;We could either put an UninterruptibleLockGuard or try/catch around the lock acquisition; it may be better to put a try/catch, since we probably don&apos;t want to block stepdown for this.&lt;/p&gt;</description>
