Description

There is a PR to make the MDS always send back a FLUSHSNAP_ACK: https://github.com/ceph/ceph/pull/4523

But I guess the clients are issuing these at times when the MDS doesn't expect them, and then the clients hang up. We should fix this on both sides if possible so it works if either end is upgraded.
