Hi, We are using nginx/0.8.15 on our front web server, mainly for caching and reverse proxy. Our cache is located in /dev/shm disk in order to obtain a better performance. Recently, we've found that sometimes the total size of the cache path would exceed the "max_size" in the configuration, and the process of "cache manager process" is quite busy, using 100% for one CPU.by wzpzning - Nginx Mailing List - English
