I have a problem with nginx-1.1.16 uses proxy_cache_lock on. 
When high load or many request to nginx, Suddenly nginx seems hang, 
no response at all. 
In netstat "SYN_RECV","CLOSE_WAIT" too many. This problem needs 
restarting nginx, and "CLOSE_WAIT" clear.

There is no problem in front-end nginx servers, but backends one.

Any clue?
