CloudLinux Guides, Scripts and Tools
LVE limits, the 508 Resource Limit error, CageFS and PHP Selector on cPanel and DirectAdmin hosting servers.
Short answer: This is the srvScripts hub for CloudLinux on shared hosting servers: what the LVE limits mean and how to read faults, fixing "508 Resource Limit Is Reached", CageFS and PHP Selector problems, upgrades, and the security stack that usually runs with it. Pick the section that matches the job.
Each page says how it was tested against the official CloudLinux documentation; our lab servers do not run CloudLinux, so those pages say so.
