Configure Server CRON for Reliable QCST Scheduled Tasks

This guide provides the Joomla Scheduled Tasks/CLI operational concept and explains why CRON is recommended for inbound email and other time-sensitive work.

Where this fits in QC Support Ticket

QCST 1.0.42 installs five current Joomla Scheduled Task routines: Entitlement Revalidation, Email Delivery Retry, Customer Reminders, Inbound Mailboxes, and Scheduled Reports. Older SLA Automation and Webhook Delivery task types are retired and should not be recreated as current QCST routines.

Joomla Lazy Scheduler can run due tasks during site traffic, but a server CRON invoking Joomla Scheduled Tasks is the more predictable choice when inbound mail or other time-sensitive work must continue on quiet sites.

Primary location: Joomla Administrator → System → Scheduled Tasks, with QCST health summarized under QC Support Ticket → Status.

Before you begin

  • Open Joomla Scheduled Tasks and confirm the QCST task plugin is installed and enabled before changing task intervals or CRON.

How to do it

  1. In Joomla Administrator, confirm all five QCST Scheduled Tasks exist and are published at the intended cadence.
  2. Configure your hosting/server CRON to invoke Joomla's Scheduled Tasks CLI runner on a reliable interval appropriate for the site. Use the Joomla-provided CLI command/path for your installation rather than inventing a web URL.
  3. Run the CRON command manually from the same PHP/OS user context and confirm Joomla reports successful task execution.
  4. Check QCST Status and Joomla Scheduled Tasks after the run.
  5. Keep server CRON enabled on low-traffic sites, especially when Max Inbound Mailboxes need near-5-minute polling.

Important behavior and limits

  • QCST 1.0.42 has five current Scheduled Tasks. Older SLA Automation and Webhook Delivery task types are retired.
  • Lazy Scheduler depends on site traffic. Server CRON is preferable when inbound mail or other time-sensitive work must run predictably.

Current-version note

This documentation is based on QC Support Ticket 1.0.42, the package currently deployed on the QuantaCade production site. The behavior described for Configure Server CRON for Reliable QCST Scheduled Tasks should be checked against the current screen labels before applying instructions to an older QCST release.

Verify the result

  • The expected QCST routine exists once, is Published at the intended cadence, and completes without a repeated error state.

If it does not work as expected

  • If a due task does not run on a quiet site, verify server CRON rather than repeatedly changing the QCST interval.
  • For entitlement warnings, separate structural task health (missing/disabled/duplicate/slow) from temporary network/validation results.
