“cache memory”? What command are you using to get this?

As an aside, it appears you could simplify your config a bit (and make  
it more efficient as well):

server {  
listen 80;  
client\_max\_body\_size 50M;  
server\_name [www.sample.com](http://www.sample.com);  
send\_timeout 20;

```
location / {
    root /home/public;
    expires 7d;

    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;
    proxy_redirect off;
    proxy_max_temp_file_size 0;
    proxy_connect_timeout 30;

    try_files $uri $uri/ @backend;
}

location @backend {
    root /home/public;
    rewrite maintenance.html break;
    proxy_pass http://Sample;
}

```

}

Hi,

I am facing memory leak problem with nginx in my servers.

The nginx is taking more cache memory while running continuously.

I have hardly found any solutions to fix this memory leak problem.

Can any one please help me out in resolving this issue.

FYI - i have given my server nginx configuration and server detail below  
for references.

Thanks You!

Amount of memory reported in “cached” column by free corresponds  
to memory used for page cache, i.e. cache memory used for files  
read from disk.

As long as you have [at least some] free memory - it is normal  
that cached will grow. Any free memory available in system will  
be used by your OS to cache files.
