If your account often reaches the resource limits you have several options:
Check which resources are at their limits.
In most cases its a plugin, a template or generally high traffic on your website. If the website is not optimized visitors will see a 50x error.
Install cache plugin/extension for your CMS (WordPress, Joomla, etc).
If the account is on a LiteSpeed server, you may use the cache plugin from LiteSpeed for WordPress.
