[ceph-users] list-type=2 requests

Hi, Is there anybody know about list-type=2 request? GET /bucket?list-type=2&max-keys=2 We faced yesterday the 2nd big objectstore cluster outage due to this request. 1 user made the cluster down totally. The normal ceph iostat read operation is below 30k, when they deployed their release it jumped up to 350k which made rados-gateway died under the haproxy. Why ceph is so sensitive for this or what is this actually? I don't even found anything in google.
