            <title>[SERVER-32030] SyncTail::oplogApplication uses a long-running OperationContext (3.2/3.4) </title>
                <link>https://jira.mongodb.org/browse/SERVER-32030</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Replication runs a background thread for oplogApplication that lives for the duration of the mongod process. In 3.2, that thread creates a single &lt;a href=&quot;https://github.com/mongodb/mongo/blob/78a87f7580736c7fbe7ee48d8c7c00716fbc913e/src/mongo/db/repl/sync_tail.cpp#L711&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;OperationContext&lt;/a&gt; and uses it for the entire lifetime.&lt;/p&gt;

&lt;p&gt;The same lifetime is also seen in &lt;a href=&quot;https://github.com/mongodb/mongo/blob/b7d36fe1669a9752c5ae6e35269ac1bf3d0409c0/src/mongo/db/repl/sync_tail.cpp#L779&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;3.4&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;I believe that if those &lt;tt&gt;OperationContexts&lt;/tt&gt; are scoped to the main loop, as in &lt;a href=&quot;https://github.com/mongodb/mongo/blob/c85b31b5d392b71cabf87bac1ac229a5a9ad62b4/src/mongo/db/repl/sync_tail.cpp#L865-L866&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;master&lt;/a&gt;, then they would refresh frequently enough to release recovery unit resources that can impede progress of dropping collections.&lt;/p&gt;</description>
