Not able to run single command over the notebook
Hi AnmolGan81,
Thank you for reaching out to the Microsoft Fabric community forum.
The issue appears to be that the F2 SKU has limited resources, with only 4 Spark vCores available. This means you can only run one Spark session at a time, even if you're using multiple notebooks. If there's an active session in one notebook, attempting to start a new session in another notebook causes the error.
To fix this, you have to restart the capacity and manually terminate the Spark session from the notebook. Once that's done, you can easily restart the session whenever needed.
I hope my suggestions give you good ideas, if you need any further assistance, feel free to reach out.

Thank you.
What happens when you manually try to to start a new session? On occassion I will get a similar error - when I reconnect the session and run the notebook it resolves.
That gives the same error as posted most of the time I got below error for F2 capacity, when I am only executing query to create a delta table from the file, I dont know how many concurrent session an F2 Capacity can run, also I did not find any documentation related to it:
