Great. If it doesn't help, then it would be good to see the
"ganesha_stats inode" output. That script is part of the
nfs-ganesha-utils package. The output from my (idle) server looks like
this:
----------------8<-------------------
$ ./ganesha_stats.py inode

That should tell us something about the cached inodes that ganesha is
holding onto.
