    ello!

    since 2 months I have problems with the server

    i install cloduflare to reduce the load, and it works greate beacause the load go from 5 to 1

    but wordpress mu still have pics of load that make crash the server

    So. I decided move the biggest site (androidzone.org 40000 user per day) to a new hosting: VPS from liquidweb (2Gb 1 CPU)

    then i delete all plugins, and all themes, except Platinum SEO Pack and Savrix Android Market

    The load is normal (0.6) but still have pics, one or to times at day that crash apache or server

    now i've deactivate wp cron by adding define('DISABLE_WP_CRON', true);

    things seem normal in the course of 1 hour

    but what is the problem that is causing this? how to find it?

    this is the logs in one pic of high load

  2. 1) Talk to your webhost and ask them to help optimize your server.

    2) Turn on caching. A liquidweb VPS can install APC, which is great. Use that with W3TC.
