We are contacting you to inform you that we have had to throttle the
connections to your site (elgolico.es) as it was causing the apache
server you are on to run out of available connection slots. While we attempt
to avoid disruption of customer services in this case it was causing
problems for other users so we were forced to take action. If you can
redesign your site to be less process-intensive (we only throttle sites
when they are causing load in the server in addition to having many
connections - if you just have static content for example that's easy for
the machine to servce up and we can just give you more connections)
we'll be happy to review the case for you. It is also possible that you
have outgrown shared hosting and are ready for your own private server:

If you are interested in that option please contact support with any
questions you have any we'll be happy to assist you.

Mira en el panel de control de Dreamhost a ver si puedes recuperar el mensaje que te enviaron para saber un poco mas del problema.
Igualmente a ver si puedes investigar que tal vas de consumo de la CPU que tienes assignada...
Ciao!
