Hi all,

I tried to put the following directive into http {}

```
proxy_cache_path /usr/local/nginx/proxy_temp levels=1:2

```

keys\_zone=wlcstaticfiles:10m inactive=7d max\_size=200m;  
proxy\_temp\_path /usr/local/nginx/proxy\_temp; # must be on the  
same filesystem as cache

When I tried to test the configuration to see if there were something  
wrong, it crashed

[sys@k78-web1 ~]# /usr/local/nginx/sbin/nginx -t  
Segmentation fault

If I removed the above mentioned directives,  
“/usr/local/nginx/sbin/nginx -t” said it was OK.

Am I doing anything wrong?

Regards,

Hoang

Hi Igor
