Hi folks,
I've been looking into my problem with OSDs that use
up a lot of memory. Let running, I've seen them swell to
over 8 GB of resident memory. I'd really like to have some
way of limiting the maximum memory footprint of an OSD.
Is there a knob to do this?
I've just today recompiled ceph-osd with tcmalloc
turned on, so I could do some memory profiling. (The RPMS
from ceph.com don't have it turned on.) Here's an example
of what I see from pprof:

Any suggestions would be appreciated.
Thanks,
Bryan
