Sonos preventing array from stopping

[scaldeddog79]

My array wont stop and I am seeing this error in the logs:
 

Jan 23 17:25:49 Tower root: rmdir: failed to remove '/mnt/user': Device or resource busy

 

Searching the forms lead me top do a 'lsof | grep /mnt/user' to find if I maybe had a process open somewhere and It looks like sonos is locking things up.  In my Sonos app I have the media server options enabled, and I am assuming it found my music folder via Emby UPnP or maybe some other means.  Disabling the Media server discover in the app does not appears to help in the immediate term.  Also trying to kill the processes doesn't appear to be heling (they aren't going away with a kill -9).  These are the processes:

Has anyone seen this before or maybe have a way to safely stop the array since killing the processes doesn't seem to "stick"?    Any tips for how I may be able to let Sonos access my music share without it commandeering the system?
