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).

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