Drobo

5N spontaneously unmounts when I attempt to access specific folder

I have a folder on my 5N that contains several hundred time lapse jpg’s generated from a GoPro. When I attempt to read the folder in Mac Catalina, the Drobo 5n spontaneously unmounts. I’ve tried deleting the folder with trashcan and terminal commands (rm -rf) and both actions result in the drive unmounting. For the purposes of testing, I have the drive connected directly to my Mac Pro. No network hardware is in between the Drobo and my Mac. Any ideas on how to resolve this?
