What is the exact kernel version ? Ubuntu has a new tcmalloc incorporated from 3.16.0.50 kernel onwards. If you are using older kernel than this better to upgrade kernel or try building latest tcmalloc and try to see if this is happening there. Ceph is not packaging tcmalloc it is using the tcmalloc available with distro.

We stop and start the osd to bring it up again but it’s quite annoying. I’m guessing this affects Jewel as well?
