Hi,
I am facing the same issue. Could something be missing in the configuration?
I've included below that minimum number of workers is set to 8 and max at 48.
I am sending 16 requests simultaneously hoping that the other 8 workers will be created but they never get created.
You can see that in the log below, 7 workers are waiting to be created but they shouldn't wait. I have set max workers to 48.
Please help me understand the issue and provide any workarounds.
