Queued time is elevated - can this trigger a notebook failure?
Hi dbeavon3 ,
Thank you for the detailed information and understanding you provided. I apologize for any inconvenience caused.
As you mentioned, you are facing an issue with "Session is unable to register ReplId". This appears to be a new issue for Microsoft, and we appreciate you bringing it to our attention.
To ensure this is addressed effectively, I recommend you submit a support ticket directly to Microsoft using this link: https://learn.microsoft.com/en-us/power-bi/support/create-support-ticket
Thankyou.
The Livy-related error is likely a symptom rather than the root cause. Microsoft Fabric uses a custom implementation of Livy, which manages Spark sessions. The 10-minute delay might have exceeded an internal timeout, causing Livy to fail the session creation.
