'whonixcheck' goes on loop

When i run the command ‘whonixcheck’ in the terminal i see this mesage repeated for about one, two minutes:

[INFO] [whonixcheck] Tor Connection Result:
- Connecting for 12 seconds. | 100 % done. 
- Tor Circuit: established.
- Tor reports: NOTICE BOOTSTRAP PROGRESS=100 TAG=done SUMMARY="Done"
- Timesync status: not done.
- sdwdate reports: Initial time fetching in progress...

What does it mean and why it’s happening? Can it be prevented?

Works as expected. Keep you posted on progress.
