Error Code 430: Too Many Requests For Capacity

[carolina_k]

Hi,

I'm trying to run a notebook in Fabric but keep getting the below error:

I have tried to go the notebook in the stacktrace but it doesn't look like it's running.  I can't seem to find where the actively running jobs are listed in Fabric so I can cancel them.  The only solution I've found is to wait for the spark pool to stop completely and start it up again from scratch.  I've tried to add a delay to a new cell at the end of the notebook but this doesn't seem to work.  There must be a faster/more efficient way of solving this issue though...

Any help or advice that anyone can provide would be very much appreciated!  I am very very new to Fabric...

Many thanks!

Hello,

I do not understand how this is the solution. I have a F2 capacity. I am the only person on the platform. I have nothing running according to Monitor. But it still gives me a HTTP 430 message. So something must be running but I cannot see what it is. Where can I see evertyhing that is using my capacity so that I can make an informed decision on how to run my notebooks?

Agree. I'm at F8 right now - one user, one notebook, one lakehouse - and I can't both have a notebook processing a simple ELT job in one tab, and then explore a table in the onelake hub on another tab. Get: TooManyRequestsForCapacity.

This can't be right.

I figured out somewhere that the problem is related to the Spark pools. I do not fully understand the Spark pools yet but it worked significantly better when I created a new Spark pool and used that instead of using the Starter Park pool.

Hope this can work for you too.

HI @carolina_k,

I'd like to suggest you take a look at the official document about fabric notebook usage and limitations part if these help for your scenario:
