We're launching a wpmu specialized in fashion, including buddypress Fashion Blogr and the tool is great, we set up the multi-site with subdomains etc but since a while, all subdomains go down, for example http://phony-tales.fashionblogr.com
The point is that the whole platform is OK, the homepage, the admin, the buddypress features, but after running for a few hours properly, all subdomains become unable to load properly...
The whole thing is hosted on a dreamhost private server and it looks like it doesn't reach the whole RAM capacity.
We try to investigate since a few days without finding any answer to this mystery! Can somebody help ?
