Yes, that worked for me.
Before that I had excluded the dirs that I didn't want to be cached. But I couldn't deselect the /mnt/remotes share.
Now I set all shares which shall be cached and the errors are gone.
I had the same issue. Do you use the plugin "Dynamix Cache Dir" and the plugin "Unassigned Devices"?
For me the errors stopped when I disabled the plugin "Dynamix Cache Dir". Seems that this plugin tries to cache the SMB-Share.
