> Issue Type: Bug
> Components: DUCC
> Reporter: Jerry Cwiklik
> Assignee: Jerry Cwiklik
> Priority: Major
> Fix For: 3.0.0-Ducc

>
> Pull service is not polling for tasks correctly. Currently it allows threads
> to send GET requests concurrently. With many services running each with many
> threads the driver may get easily overrun.
> Instead each service should allow one GET request at a time. So there is only
> one thread pulling task at a time. Other threads block until a thread
> receives a task. If no task is given, a single thread will retry until a task
> becomes available or service is stopped. There will be no waiting on the
> driver/client side.
