Ultra task retry itself

Hi,

I have a ultra task. The ultra task receive HTTP request and take query string as parameter and process it afterwards. Very simple.

The problem I found is that, If I only call the Ultra url once, the request will automatically be spawned to additional 4 times. Meaning that If i call the ultra task once, the task run 5 times in total.

I don’t know why and seems like a bug to me. I know ultra has retry mechanism when requests fails in the middle, but in my case, all requests run successfully.

Does anyone have the same issue?
