Description

For TRSP, and also RTP in branch-2.0 and branch-2.1, if we fail to assign or unassign a region, we will set the procedure to WAITING_TIMEOUT state, and rely on the ProcedureEvent in RegionStateNode to wake us up later. But after restarting, we do not suspend the ProcedureEvent in RSN, and also do not add the procedure to the ProcedureEvent's suspending queue, so we will hang there forever as no one will wake us up.
