[ceph-users] Nautilus OSD memory consumption?

The OOM-killer is on the rampage and striking down hapless OSDs when the cluster is under heavy client IO. The memory target does not seem to be much of a limit, is this intentional? root@cnx-11:~# ceph-conf --show-config|fgrep osd_memory_target osd_memory_target = 4294967296 osd_memory_target_cgroup_limit_ratio = 0.800000 root@cnx-31:~# pmap 4327|fgrep total total 6794892K Are there any tips for controlling the OSD memory consumption? The hosts involved have 128GB or 192GB memory, 12 x OSDs (SATA), so even with 4GB per OSD there should be a large amount of free memory.
