We have used tmpfs to mount frequently used media application cache serving.
We have also mounted rest applications on disk where we are facing similar
issues of max_size being breached . Please find below details for your
reference :

# du -sh /cache/*
245G    /cache/12007
161G    /cache/12152

# grep a12007 /etc/nginx/nginx.conf
proxy_cache_path    /cache/12007 keys_zone=a12007:200m levels=1:2
max_size=200g inactive=10d;
# grep a12152 /etc/nginx/nginx.conf
proxy_cache_path    /cache/12152 keys_zone=a12152:200m levels=1:2
max_size=100g inactive=10d;

Please let us what went wrong here and how this can be corrected.
