These are the resources that each cPanel account is limited to, these are in place to help prevent a single user from utilizing a significant chunk of the server resources and subsequently affecting everyone else. If you are reaching your limits persistently and do not know why, please open a support ticket and we'll be happy to take a look.
- CPU: The % of a core (100% is representative of 1 full CPU core) that your account is limited to before throttling occurs, no errors will occur from hitting this limit as your processes are throttled/slowed down instead of killed.
- Memory: The maximum amount of physical memory that your account can utilize, errors will occur if this limit is reached.
- Entry Processes: Counted as processes that act as entries such as processes into PHP and MySQL, however, this isn't a direct limit on how many users can visit your website(s). This will result in errors if it is reached.
All cPanel accounts have an IOPS limit of 1024 and an inode hard limit of 1,000,000. Once the inode limit is reached, you will be unable to write any more files and will be required to remove some data to regain functionality.
