Just fyi, I also have growing memory on OSD, and I have the same logs: "libceph: osd4 172.20.11.32:6801 socket closed" in the RBD clients I traced that problem and correlated it to some cephx issue in the OSD some time ago in this thread http://www.mail-archive.com/ceph-devel@xxxxxxxxxxxxxxx/msg10634.html but the thread kind of died without a solution ...
