      Description

      This feels very similar to SERVER-32521 which I filed a while back but now I'm on Atlas replica set (which was upgraded from 3.6 to 4.0) and I see every five minutes in the logs:

      2018-08-31T00:09:09.665+0000 I COMMAND  [LogicalSessionCacheRefresh] command config.$cmd command: createIndexes { createIndexes: "system.sessions", indexes: [ { key: { lastUse: 1 }, name: "lsidTTLIndex", expireAfterSeconds: 1800 } ], $db: "config" } numYields:0 reslen:275 locks:{ Global: { acquireCount: { r: 2, w: 2 } }, Database: { acquireCount: { w: 1, W: 1 }, acquireWaitCount: { W: 1 }, timeAcquiringMicros: { W: 464030 } }, Collection: { acquireCount: { w: 1 } } } protocol:op_msg 464ms
