507 Insufficient Storage

Question

Some of our customers are reporting a '507 Insufficient Storage' error when accessing certain websites. Sites with a large number of images are failing to load, and when users are editing multiple items across different browser tabs. What could be causing this?"

Answer

When a domain displays a "507 Insufficient Storage," this is because the LSPHP workers need to be increased. To resolve this, it's recommended to increase the number of LSAPI children, disable LSAPI reject mode, and tune Apache.

To make these changes, you'll need to update the /etc/apache2/conf.d/lsapi.conf:

1. Access your server via SSH as the root user.
2. Using your favorite editor, modify the file "/etc/apache2/conf.d/lsapi.conf".
3. Within the file, add "lsapi_disable_reject_mode On"
4. Find the "lsapi_backend_children" directive and uncomment the line.
5. Increase the original value.
6. Save the file.
7. Restart Apache:

   /scripts/restartsrv_apache

8. Remount CageFS

   cagefsctl --remount-all

Please note, you will also want to tune Apache for MaxRequestWorkers to prevent the system from becoming overloaded. Please review the "Tuning MaxRequestWorkers for Apache" article under our Additional Resources section.
