Description

Every few seconds on a 14.2.11 OSD I see an op with age close to 2^32:

        {

                        "time": "2020-10-10 10:50:34.302612",

                    },
                    {
                        "time": "2020-10-10 10:50:34.302613",

                    },
                    {
                        "time": "2020-10-10 10:50:34.302616",
                        "event": "queued_for_pg" 
                    }
                ]
            }
        },

The op is fine and completes quickly so maybe this is an initialization bug?
