                            <comment id="4849187" author="dianna.hohensee" created="Thu, 22 Sep 2022 18:01:04 +0000"  >&lt;p&gt;This task is being put on hold, along with the project. The latest impediment to solving this ticket&apos;s problem is that there exists &lt;a href=&quot;https://github.com/mongodb/mongo/blob/2f2d776a7291ceb79d6ebb8dc214f8887300cc56/src/mongo/db/repl/rollback_impl.cpp#L287-L289&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;a category of operations that are not interrupt by rollback&lt;/a&gt;, which in theory could take storage cursors unassociated with the CursorManager.&lt;/p&gt;</comment>
                            <comment id="4736073" author="dianna.hohensee" created="Mon, 8 Aug 2022 20:38:29 +0000"  >&lt;p&gt;It appears that we modify read concern settings (prepared conflict) in &lt;a href=&quot;https://github.com/mongodb/mongo/blob/da1b994b05bba3b15cadd5138fc3dcd3687c7f91/src/mongo/db/pipeline/document_source_writer.h#L55&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;DocumentSourceWriter&lt;/a&gt;. The problem with this is that if the high level code has a AutoGetLockFree*, we&apos;ve already got a storage snapshot open: read concern is normally manipulated in the AutoGet* or earlier layers. It works today because &lt;a href=&quot;https://github.com/mongodb/mongo/blob/da1b994b05bba3b15cadd5138fc3dcd3687c7f91/src/mongo/db/commands/run_aggregate.cpp#L657&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;we happen not to hold AutoGet* across runAggregate&apos;s use of DocumentSourceWriter&lt;/a&gt;. I was trying to hold locks across this, to hold a lock across registration of CursorManager::registerCursor for concurrency control with replication rollback.&lt;/p&gt;</comment>
