If the process is aborted, all its tasks are dead. You probably mean
aborting the task. Then just do not abort it if you steel need it.

task body Task_type is
begin
   loop
      select
         accept Start; -- Wait for a session to start
         ... -- Do what has to be done in this session
      or terminate; -- Complete when no more needed
      end select;
   end loop;
end Task_type;
