Description on the Symptoms

After restarting DAQ, the missing tiles can be seen on the occupancy plots on Rootspy (see an example image to the right).

Solution

  1. Stop the current run.
  2. Completely restart Coda (by pressing STOP button on the RCM GUI).
  3. Start Coda normally (Configure->Download->Prestart->Start)
  4. Call DIRC expert if problem was not resolved.
