HTTP 508 Loop Detected (Resource Limit Is Reached)

Either the server detected an infinite loop (WebDAV) or — much more often — a cPanel/CloudLinux host is saying your account hit its resource limits.

Meaning

On shared hosting, “508 Resource Limit Is Reached” means LVE limits (entry processes, CPU, memory) were exceeded: too many simultaneous PHP processes, a traffic spike, bots, or slow plugins. In WebDAV, 508 means a bind/collection loop.

Common causes

  • Shared hosting entry-process (EP) limit reached by concurrent requests
  • Bots/crawlers or an attack flooding the site
  • Slow PHP (heavy plugins, no caching) holding processes
  • WebDAV collection binding to itself

⚡ Quick fix

  1. Enable page caching so PHP runs less
  2. Block abusive bots (Cloudflare, robots, rate limits)
  3. Check cPanel → Resource Usage and upgrade the plan if legitimate

Detailed fix by platform

WordPress

  1. bash
    # install a page-cache plugin and limit heartbeat/cron
define('DISABLE_WP_CRON', true);   // run wp-cron from a real cron job instead

Apache

  1. apache
    # .htaccess: block a bad bot by user agent
RewriteCond %{HTTP_USER_AGENT} (BadBot|AhrefsBot) [NC]
RewriteRule .* - [F,L]

How to diagnose

  1. Usage — cPanel Resource Usage graphs (EP, CPU, PMEM)
  2. Traffic — Access logs for bursts/bots
  3. Slow pages — Which URLs take longest?
