   on the safe side..

   I have the same problem. Any luck now?. My site, was also blocked by my hosting company.
   No ideas. (You have abou 450 blogs?) how much can they delve in theming, plugins and such?
   Maybe we can find a common factor?.

   Man anyone has any solution to this?
   My dedicated server is now facing this issue due to one of my own WordPress websites.

   My dedicated server is now facing this issue due to one of my own WordPress websites.

   Whilst this doesn't fix the causation, you can disable WordPress's cron system, and instead use a normal crontab call (which most shared hosts don't support, thus WordPresses builtin system which works on most).

   So, what you need to do to replace wp-cron with crontab which might fix your issue in this case:

   • Disable Cron spawning - define('DISABLE_WP_CRON', true); in your wp-config.php - Warning: Do not define this without doing something about spawning cron
   • Create a cron job to call http://site.com/wp-cron.php?doing_wp_cron through something such as wget or curl or similar every 5 minutes, or 15minutes, whatever you want
   • Schedule a post to be published in 5 minutes time, Check your post gets published after 5 minutes without accessing the WordPress admin area

    Hi Guys,

    below information is only with people who own their servers

    I just thought to share that, I recently installed CloudLinux on my Dedicated server so that a site does not end up taking all the server resources.

    I was skeptical at first as I had found not found a single solution for my WordPress site, which just kept on crashing server even after multiple reboots. I never got a chance to even suspend the site myself.

    By server admins did that for me, and then suspened that domain which was causing problem. I installed CloudLinux, and then unsuspended the site, deleted all plugins and the site was working fine.

    Now one thing I can rest assured is that other sites won't be affected due to one site's issue. I tried all methods but most are not practical to do if you manage lot of clients who use WordPress.

    For now am just going to use limited plugins until someone finds a proper solution. I hope such things do not happen with WordPress 3.2, whenever it releases.
