We have increased the cache on our MDS which makes this issue mostly go away.
It is due to an interaction between the MDS and the ganesha NFS server which
keeps its own cache. I believe newer versions of ganesha can deal with it.

I don’t know if it is related. But we are routinely get warning about 1-4
clients failed to respond to cache pressure. But it seems to be harmless.
We are running 16.2.6, 2 active MDSes, over 20 kernel cephfs clients, with the
latest 5.11 kernel from Ubuntu.
