ADOP Cutover with Request running

So, simple question: I ran ADOP Prepare, Apply and Finalize phase,

the system starts a Concurrent Request

The ADOP Cutover starts

Problem is, this Concurrent Request runs a very long time. A really long time.

What solution is foreseen for this issue: when the Cutover phase runs, it tries to stop the Concurrent Manager, but it waits until all Requests have completed.

Is there a time-out foreseen for this case ?
