A 508 Resource Limit Reached message means your account hit a plan limit at that moment, not that the server is down.
THE LIMITS
- CPU: processing time
- Physical memory: RAM
- Entry processes: how many requests run at once
- I/O and IOPS: disk throughput
CHECKING
cPanel > Resource Usage, then Details, shows graphs over time and names which limit was hit and when.
WHY IT HAPPENS
No page caching, so every visit runs the full application A traffic spike, legitimate or otherwise Bot or attack traffic wp-cron overload Heavy plugins, particularly statistics, link-checking and live chat A backup or import running during peak hours A genuinely growing site on a plan that no longer fits
FIXING IT
Enable caching first, as it usually solves the problem outright. Move backups and imports to quiet hours. Remove or replace heavy plugins. Block abusive bots, ideally with Cloudflare. Set up the cron job correctly.
If usage stays high after all of that, the site has outgrown the plan. Open a ticket and we will look at the graphs with you.
