Leaf level sequencer's stop_sequences() is terminating virtual sequence which is running on virtual sequencer

In reply to kerulmodi:

If you are following the UVM User Manual you do not have to take care for register/unregister any object.
The key weakness I see in you code is you are using signals in a transaction level object (your sequencer). Furthermore you do not need any p_sequencer declaration.
Additionally it is unclear for me what are yxou doing with your process object.
