Diskspace full despite max_size being less than disk size

[jaretclifton]

For testing I've allocated 750GB to my VM and the lancache installer has set the max_size for caches to be 500GB (500000m in /etc/nginx/lancache/caches) yet the disk hit 100% space used yesterday. I'm wondering if the individual lines containing max_size=500000m should be removed and one main max_size variable added for all caches?
