On CloudLinux systems, Resource Usage can show limits and faults for resources such as CPU, entry processes, physical memory, process count, I/O, and IOPS. A fault indicates that a configured resource limit was reached.
- Choose a time range that includes the failure.
- Compare fault timestamps with the website request, cron job, import, backup, or application task that was running.
- Look for repeated faults of the same type rather than relying only on current usage.
- Reduce or reschedule the workload that correlates with the faults.
- For WordPress, investigate plugins, themes, scheduled tasks, bots, or database-heavy actions that line up with the event.
CPU throttling can make a site slower, while memory/process/entry-process faults can interrupt requests. The exact limits are account-specific and should not be assumed from generic documentation.
