Apache 2.2.22 - Random Vhost misrouting

I have a Apache 2.2.22 + PHP 5.4.9 running on a Ubuntu 12.04 I’m hosting three sites here. For that, i have 2 virtual host pointing to three differents folders. For example, this is one Vhost for domain1 Code: <VirtualHost *:80> ServerName domain1.com ServerAlias www.domain1.com ServerAdmin support@server.com DocumentRoot /mnt/htdocs/domain1.com/public <Directory /> Options FollowSymLinks AllowOverride None </Directory> <Directory /mnt/htdocs/domain1.com/public> Options Indexes FollowSymLinks MultiViews AllowOverride All Order allow,deny allow from all </Directory> ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/ <Directory “/usr/lib/cgi-bin”> AllowOverride None Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch Order allow,deny Allow from all </Directory> ErrorLog ${APACHE_LOG_DIR}/domain1.com-error.log CustomLog ${APACHE_LOG_DIR}/domain1.com-access.log combined </VirtualHost> The this here is that the 1% of the hits goes to incorrect folder. the other 99% goes to the correct folder and resolve the correct domain/code. Example of the error in domain1.com’s error log Code:

[Fri Feb 14 15:21:45 2014] [error] [client 10.183.250.134] PHP Fatal error: Class ‘Sitemap\SitemapServiceProvider’ not found in /mnt/htdocs/domain1.com/vendor/laravel/framework/src/Illuminate/Foundation/ProviderRepository.php on line 123, referer: http://www.site2.com/someurl

This service provider doesn’t exists because domain2.com is routed to domain1.com’s folder. This error is COMPLETELY RANDOM. If I reload the error page, the site render ok. I checked all the lines of vhosts, erasing all the non critical to keep it simple but the error continues. Any thought?
