The loopback network driver sending task is placed in the LPWORK queue, which may result in delayed scheduling when the CPU usage reaches 100%, leading to the timely sending of cached messages from the loopback network driver and causing issues with post waitsem being too late​.we decied to set loopback sending task to the HPWORK queue.
