Hello,  
I am using PHP to connect to memcache.

I connect memcache service in the PHP code as follows:  
$memcache = new Memcache;  
$memcache-\>connect(‘127.0.0.1’, 11211); //connect to memcached server

Then when I connect to NGX server, I got 500 or 502 error.

However, if I run the memcache using php test.php directly, I can  
connect to memcache server successfully.

I am using php-fpm.

Does anyone encounter the similar issue before?

Thanks,  
Yanxin

Hello Igor,  
Thank you for your direction.

I searched for “nginx 104: Connection reset by peer”

In the forum  
[http://forum.slicehost.com/comments.php?DiscussionID=433](http://forum.slicehost.com/comments.php?DiscussionID=433)

Someone suggest to restart fastcgi.

I did restart php-fpm then, memcached is working now.

Hopefully my post is helpful to other members.
