SaaS Workers Limitations

Workers in SaaS JFrog environments have the following limitations:

• Maximum execution time: 20 seconds
• Maximum CPU time: 1 second
• Maximum consumed memory: 64 MB
• Maximum script size: 100,000 characters
• Maximum execution rate:
• Up to 1,200 executions per second
• Up to 120 executions per second sustained for 1 minute

Failure handling

If a Worker execution exceeds any of the resource limits above, the execution fails. Failed executions follow this backoff mechanism:

• Failed Worker executions trigger an exponential backoff with a maximum delay of 17 minutes
• A Worker is blocked after 10 failed executions within 10 minutes
• The backoff exponent and failure counters are reset every 24 hours
• Failures caused by queue wait time do not trigger backoff
• Test runs from the Worker edit page do not trigger backoff

When a Worker is in backoff or has another warning, the Workers list shows a warning icon next to the Worker name. Hover over the icon to see the reason. You can dismiss a warning. If a Worker has more than one warning, you can open a dialog to view all of them. Executions that were stopped because of backoff appear in Workers Troubleshooting.
