I am now seeing the exact same issues you are reporting. A heap release did nothing for me.
The only odd thing I'm doing is migrating data in cephfs from one pool to another. The process looks something like the following:
TARGET_DIR=/media/cephfs/labs/
TARGET_POOL="cephfs_ec_data"
TARGET_POOL="cephfs_ec_data"
setfattr -n ceph.dir.layout.pool -v ${TARGET_POOL} ${TARGET_DIR}
#for every file
##NEWFILE="${file}.ec"
##cp "${file}" "${NEWFILE}"
##mv "${NEWFILE}" "${file}"
I have a fear that this process may not be releasing the inode of ${file} and deleting the objects from RADOS. But, I'm not sure that would have much to do with MDS outside tracking an inode that isn't accessible anymore.

I'll try to monitor memory to see when exactly it's growing, it's seem to grow time to time, but not continously.
