            <title>[SERVER-79682] ShardsvrReshardCollection Can Hang If Stepdown Occurs Shortly After Stepping Up</title>
                <link>https://jira.mongodb.org/browse/SERVER-79682</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The &lt;a href=&quot;https://github.com/10gen/mongo/blob/f6628e802ff035ca40fbfdba81f35734ff5bb901/src/mongo/db/s/shardsvr_reshard_collection_command.cpp#L87-L113&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;ShardsvrReshardCollection command&lt;/a&gt; does not flag the operation context to be interrupted during a stepdown, which is commonly done by &lt;a href=&quot;https://github.com/10gen/mongo/blob/fe6098e102ae84e9b0ee9afd0c30dd59c9b8a6ea/src/mongo/db/s/shardsvr_abort_reshard_collection_command.cpp#L84&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;other commands&lt;/a&gt;. This means that when calling &lt;a href=&quot;https://github.com/10gen/mongo/blob/f6628e802ff035ca40fbfdba81f35734ff5bb901/src/mongo/db/s/shardsvr_reshard_collection_command.cpp#L106-L108&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;getOrCreateInstance&lt;/a&gt;, it&apos;s possible to hang in the call to &lt;a href=&quot;https://github.com/10gen/mongo/blob/b1386222ecc66e68d45c667405ce961811564b31/src/mongo/db/s/sharding_ddl_coordinator_service.cpp#L270-L271&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;_waitForRecoveryCompletion&lt;/a&gt; when &lt;a href=&quot;https://github.com/10gen/mongo/blob/b1386222ecc66e68d45c667405ce961811564b31/src/mongo/db/s/sharding_ddl_coordinator_service.cpp#L235&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;waiting for the state&lt;/a&gt; to reach kRecovered. After a stepdown, the state will be &lt;a href=&quot;https://github.com/10gen/mongo/blob/b1386222ecc66e68d45c667405ce961811564b31/src/mongo/db/s/sharding_ddl_coordinator_service.cpp#L199-L203&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;set to kPaused&lt;/a&gt;, so it&apos;s necessary that the operation context be interrupted at stepdown to avoid the hang.&lt;/p&gt;
