[ceph-users] Re: Nautilus: (Minority of) OSDs with huge buffer_anon usage - triggering OOMkiller in worst cases.

I should note that these OSDs also drop out of the pool as part of their symptoms - it's not clear to me at the moment if they drop out *because* of the memory, or if the buffer_pool is growing large because it's buffering communications that aren't getting to the cluster [and hence they drop out].
