Help with Nginx Vhost ( Server Blocks) that work intermittently

Hi, Im on a Ubuntu 14.04 droplet with Lemp. I have 4 domains pointing to the server but only the default vhost works correctly. The other vhost work for a minute or 2 and then hang and then they work again and that goes on and on.

1 domain was for larval development 2 for blogs on wordpress 1 for playing with new frameworks

I’ve follow mostly DO tutorial but I used other sources too. I’ve checked the nginx access and error logs with nothing to explained this behaviour.

Im new to nginx I though had understood it but now is not working as it should.

Any ideas on what could be the cause of the problems and what should I do to fix them.

**in /etc/nginx/ **

My nginx.conf – mostly intact

worker_processes 2;
pid /run/nginx.pid;

	worker_connections 768;
	# multi_accept on;
}

my drop.conf file -> I read was a good practice

location = /robots.txt  { access_log off; log_not_found off; }
	location = /favicon.ico { access_log off; log_not_found off; }	
	location ~ /\.          { access_log off; log_not_found off; deny all; }
	location ~ ~$           { access_log off; log_not_found off; deny all; }

My php.conf file -> to make available php to the vhost

location ~ \.php$ {
        try_files $uri =404;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass unix:/var/run/php5-fpm.sock;
        fastcgi_index index.php;
        include fastcgi_params;
        }

my wp.conf file -> for passing it to the domains wp host

# WordPress single blog rules.

location / {
	try_files $uri $uri/ /index.php?$args;
}

# Add trailing slash to */wp-admin requests.
rewrite /wp-admin$ $scheme://$host$uri/ permanent;

# Directives to send expires headers and turn off 404 error logging.

       access_log off; log_not_found off; expires max;
}

**in /etc/nginx/sites-available/ ** the default vhost conf this the only one that works correctly you can see it on ambumec.com
