Fault types
- CPU faults mean the account needed more CPU than allowed.
- Memory faults mean scripts exceeded memory limits.
- Entry process faults mean too many simultaneous dynamic requests.
- IO faults mean disk throughput limits were reached.
Common causes
Traffic spikes, bad plugins, brute-force attacks, slow database queries, backup jobs, import scripts, and poorly configured cron jobs can all cause faults.
Fix path
Review logs, identify the process or URL causing load, optimize the application, block abusive traffic, adjust cron schedules, or upgrade the plan when usage is legitimate.
Shared hosting impact
CloudLinux and CageFS protect the whole server by isolating users and limiting runaway accounts. When a site hits limits, the fix may be optimization, malware cleanup, bot blocking, plan upgrade, or moving to VPS/dedicated hosting.
