SuperDuper! & Capture One Pro

I'm going to submit this to support, but has anyone else had any issues with COP while running a SuperDuper! cloning operation? Since updating COP from version 9 to 11, even if COP is just sitting idle in the background, then SuperDuper! starts one of my daily scheduled copies (either for my startup disk or the drive where I store all my masters), COP starts gobbling up all available RAM and then fills up all available virtual memory until my boot drive is full (greater than 50GB where normally it uses only about 2GB). This will be a problem when my shooting season picks up, since I run those cloning scripts in the evening after I'm home from shooting and done importing the photos, but when I'll be going through them for my first look. This is on a 2008 Mac Pro running El Capitan.
