            <title>[SERVER-48200] Audit and fix session-&gt;open_cursor calls to handle EBUSY</title>
                <link>https://jira.mongodb.org/browse/SERVER-48200</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;After we removed Collection locking for oplog readers (they only need Global IS), this stopped protecting such readers from concurrent validate commands locking the WiredTiger oplog collection&apos;s table with calls to WT verify().  Thus, open_cursor() can now return EBUSY, but only for the oplog collection.  This is captured and handled for most cursor usage via WiredTigerSession&apos;s cursor cache, but we also have some internal code in wiredtiger_kv_engine.cpp and wiredtiger_record_store.cpp that bypasses this and calls open_cursor() themselves.  These callers need to also check for EBUSY.&lt;/p&gt;</description>
