This almost certainly means that you have a corrupted file system.
NOTIFY YOUR SYSTEM MANAGER.
The following directory is part of the cycle:
  /nfs/localhost/fex/spool

What do you get for:

btrfs subvolume list -to /nfs/localhost/fex

root@tsmsrvj:~# btrfs subvolume list -to /nfs/localhost/fex
ERROR: not a btrfs filesystem: /nfs/localhost/fex
ERROR: can't access '/nfs/localhost/fex'


root@tsmsrvj:~# mount | grep localhost
