Resource limit reached

Symptoms

The site returns errors such as "resource limit reached", "too many processes" or a 503 status.
The site is slow at busy times, then recovers.
Email, database or cron tasks stop working for a while.

Common causes

Traffic is higher than the plan can handle.
A plugin, script or cron job uses too much CPU, memory or processes.
Disk space or inodes (the number of files) are full.
The database is large, or has many slow queries.

Safe initial checks

Open resource usage in the hosting panel. See Resource usage and logs.
Check disk and file counts for the account. Large mail or backup folders are common causes.
Check the cron jobs and recent plugin installs. See Cron jobs.

Step-by-step solutions

Heavy script or cron job. Reduce how often it runs, or fix the script. See Cron jobs.
Full disk or inode limit. Remove unneeded files, old backups, and large logs, after making a backup. See Website backups.
Traffic too high for plan. Compare the usage with your plan, and upgrade if the load is normal and expected.
Slow application. Turn off unused plugins, and clear caches the application created.

How to confirm the issue is fixed

Resource usage stays within the plan limits during a normal day.
The site responds normally at busy times.

When to contact support

Contact support if usage is within your plan limits and the errors continue, or if you need a higher limit.
