This looks like http://tracker.ceph.com/issues/38040. This is a server side issue, so no point in upgrading the kernel. It's still present in luminous, but there is an easy workaround -- try decreasing "osd map message max" as described in the thread linked from the description. Thanks, Ilya _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
