An Azure service that is used to automate, configure, and install updates across hybrid environments.
Hello !
Thank you for posting on MS Learn Q&A.
Based on what you shared I think that hybrid runbook worker group is receiving jobs faster than the workers can pick them up.
A single active HW generally picks up around 4 jobs every 30 seconds and if more jobs are pushed to the same HW group in that window and no other worker picks them up, Azure Automation can suspend the jobs with this message. https://learn.microsoft.com/en-us/azure/automation/troubleshoot/extension-based-hybrid-runbook-worker
So what you can do is to scale out the HW group or reduce simultaneous job starts. If you are already running only a few jobs then the next focus should be worker health network connectivity to Azure Automation and Microsoft SMA event logs.
