Resolution

  1. Confirm issue via the following steps to ensure proper troubleshooting approach.
  2. Go to Windows Start Menu, click on Computer or My Computer.
  3. Go to the following location:
    • Windows 32 Bit - C:\Program Files\Daktronics\Nucleus Server\Logs
    • Windows 64 Bit - C:\Program Files (x86)\Daktronics\Nucleus Server\Logs
  4. Open System.log and scroll towards the bottom of log file.
  5. Do you see a timestamp every 30 seconds or more?
    • Yes - Contact Daktronics Technical Support for assistance.
      • Some time stamps may show 5-6 at the same time, and then show several minutes between the next set of events.
      • One good way to test issue, is stop the Nucleus Server, Rename the Error.log and System.log and start the service. This will generate a clean/fresh log, you can count the minutes or seconds between the first time stamp in the system log, to the final time stamp saying Nucleus Server Successfully started.
      • This is a sample, of how the time stamps would or could appear.
    • No - Continue troubleshooting with other KB Articles.
