Woocommerce Causes admin-ajax.php to freeze

I am running the Bazar theme. When more than 100 people come to my site I get an internal server error due to to many processes being run. My host is Hostgator where they only allow 25 processes. Because these processes freeze (wp-admin/admin-ajax.php), it ends up taking down my site. I need help fixing this issue so that I can sell things on my site. I know its woocommerce because I first disabled the theme and the problem still existed. Then I deactivated all plugins then the processes went back to 1. Then one by one I activated the plugins where were basically ( yoast seo, akismet, wp-super cache, google analytics, and quantcast). When I activated woocommerce the process went to 22 on hostgator and I got the internal server error again which were all the same one ” admin-ajax.php” Please help
