Admin/Phpmylogin/Mail login 502 Badgateway

Hey guys,
I tried to search everywhere buy I couldn't get any of the methods to work out,
I followed this guide :
http://www.howtoforge.com/perfect-server-centos-6.4-x86_64-nginx-dovecot-ispconfig-3

Installed everything perfectly, i did connect to the admin page and add my sites and dns, etc but then again after i went back and added the phpmyadmin nginx directive using the ispconfig web interface.

I then restarted the vps and from then on i cannot open the admin or phpmyadmin or the webmail
it just gives me a 502 Bad Gateway error.

I also get this too when try to start php-fpm
~]# service php-fpm status
php-fpm dead but subsys locked
Here is the log:

2013/11/11 23:53:01 [crit] 8178#0: *31 connect() to unix:/var/lib/php5-fpm/ispconfig.sock failed (2: No such file or directory) while connecting to upstream, client: 2$

How I got it to work :
I think it was some memory issue with the php-fpm process, i was just testing it on a vps with 1gb of ram and when i disabled the antivirus, and then started up php-fpm, it worked.

Thanks for the help guys and you are doing an awesome work!!
