In reply to ksiddav:
Any solutions found? Facing the same situation here.
my sequence is simple.
grab(p_sequencer.path_to_sequencer_of_the_bus_agent);
p_sequencer.regmodel.path_to_reg.write(status,value);
ungrab(p_sequencer.path_to_sequencer_of_the_bus_agent);
It will hang, but if i take out the grab/ungrab it will proceed normally.
