I have been asking before[1]. Since Nautilus upgrade I am having
these, with a total node failure as a result(?). Was not expecting
this in my 'low load' setup. Maybe now someone can help resolving

https://tracker.ceph.com/issues.
Just a wild guess: do you have a lot of snapshots (> ~400)? If so,
that's probably the problem. See [1] and [2].
