i receive "Resource Limit Reached" Few Times, What to Do?
High Resource Usage (HRU) means the account (site) was using more then its share of CPU and/or RAM for an extended period of time
In almost all cases x10hosting has found that excessive resource usage stems from:
Out of date scripts
Excessive plugins, themes, addons
Poorly coded plugins, themes, addons
Not taking security measures such as secure wp-login\xml-rpc so bots drive up resource usage
Not keeping a database cleaned up, a forum or Wordpress blog with 50,000 spam users will use a lot of CPU on any user processing
Crons that do intense database or other processing
