Nginx Issue

[gmk.jaga]

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!
