                    <description>&lt;p&gt;The applyOps command will acquire the &lt;a href=&quot;https://github.com/mongodb/mongo/blob/249a278ec1f5f45fc002093f9781659f8b56cc0e/src/mongo/db/repl/apply_ops.cpp#L409&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;global lock in X mode&lt;/a&gt;&#160;and then apply the&#160;&lt;a href=&quot;https://github.com/mongodb/mongo/blob/46f91e5bd299bdfb6618c3fe8a82df68eadd30b8/src/mongo/db/repl/oplog.cpp#L977&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;nested applyOps object&lt;/a&gt;, which will recursively call into &lt;a href=&quot;https://github.com/mongodb/mongo/blob/3fa7f2ae9aad0e9754209fcbcc45851b8acc7b40/src/mongo/db/repl/apply_ops.cpp#L380&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;applyOps()&lt;/a&gt;. While holding the global X lock, the applyOps command can hit a &lt;a href=&quot;https://github.com/mongodb/mongo/blob/46f91e5bd299bdfb6618c3fe8a82df68eadd30b8/src/mongo/db/repl/apply_ops.cpp#L512&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;tenantMigrationConflict&lt;/a&gt; and wait for &lt;a href=&quot;https://github.com/mongodb/mongo/blob/46f91e5bd299bdfb6618c3fe8a82df68eadd30b8/src/mongo/db/repl/apply_ops.cpp#L516&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;migration commit/abort&lt;/a&gt; without yielding the lock.&lt;/p&gt;</description>
