Hello ceph users,

I've seen threads about Luminous OSDs using more memory than they should 
due to some memory accounting bugs.  Does this issue apply to ceph-fuse 
also?

After upgrading to the latest ceph-fuse luminous client (12.2.1), we see 
some ceph-fuse processes using excessive memory.  We are using all the 
defaults for client memory sizes, except increased client_oc_size to 
2GB.  Yet some ceph-fuse processes have RSS growing to 16GB and even 
more.  Any ideas?
