Sebastien,
I'm not totally sure yet, but everything is still working.
Sage and Greg,
I copied my glance image pool per the posting I mentioned previously, and everything works when I use the ceph tools. I can export rbds from the new pool and delete them as well.
I noticed that the copied images pool does not work with glance.
I get this error when I try to create images in the new pool. If I put the old pool back, I can create images no problem.
Is there something I'm missing in glance that I need to work with a pool created in bobtail? I'm using Openstack Folsom.

Dave,
Just to be sure, did the log max recent=10000 _completely_ stod the
memory leak or did it slow it down?
Thanks!
