                <link>https://jira.mongodb.org/browse/SERVER-78036</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;After &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-60466&quot; title=&quot;Support drivers gossiping signed $clusterTimes to replica set --shardsvrs before addShard is run&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-60466&quot;&gt;&lt;del&gt;SERVER-60466&lt;/del&gt;&lt;/a&gt;, a mongod started with --shardsvr but does not yet have a shard identity would temporarily use the replica set version of the &lt;a href=&quot;https://github.com/10gen/mongo/blob/cd0be4aab3f70b77f07c582f9e05cabdd0264c3f/src/mongo/db/mongod_main.cpp#L801-L802&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;LogicalTimeValidator&lt;/a&gt;, which would later get replaced by sharded version of the &lt;a href=&quot;https://github.com/10gen/mongo/blob/cd0be4aab3f70b77f07c582f9e05cabdd0264c3f/src/mongo/s/sharding_initialization.cpp#L214&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;LogicalTimeValidator&lt;/a&gt; during sharding initialization. The LogicalTimeValidator is a unique pointer decoration on the ServiceContext. As a result, once the replica set LogicalTimeValidator is replaced by the sharded replica set. The replica set LogicalTimeValidator object would become invalid and could lead to segmentation fault as seen in BF-29030. One resolution would be to make the LogicalTimeValidator a shared_ptr decoration so threads that have the replica set LogicalTimeValidator while sharding initialization occurs can continue to use it until they are done. &lt;/p&gt;</description>
