            <title>[SERVER-50176] The shardVersion recovery task runs on a fixed-size executor</title>
                <link>https://jira.mongodb.org/browse/SERVER-50176</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Currently, the &lt;tt&gt;shardVersion&lt;/tt&gt; recovery task is &lt;a href=&quot;https://github.com/mongodb/mongo/blob/21d5a8e5bd822e71e5fb8feb2f9e71a7e8cf25f9/src/mongo/db/s/shard_filtering_metadata_refresh.cpp#L89&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;scheduled on a fixed-size executor&lt;/a&gt;. What is worse, the &quot;opportunistic recovery&quot; task, which we spawn on step-up, runs on the same fixed-size executor and does a &lt;a href=&quot;https://github.com/mongodb/mongo/blob/21d5a8e5bd822e71e5fb8feb2f9e71a7e8cf25f9/src/mongo/db/s/migration_util.cpp#L814&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;blocking wait&lt;/a&gt; for the &lt;tt&gt;shardVersion&lt;/tt&gt; recovery to complete, which is this is deadlock-prone.&lt;/p&gt;

&lt;p&gt;The &lt;tt&gt;shardVersion&lt;/tt&gt; recovery task must instead use the sharding unilimited size executor.&lt;/p&gt;</description>
