TitleExtremeWireless logs show floor plans repeatedly deleted and imported
Symptoms

  • Message logs include:
Minor	Location Engine	Configuration change: Floor /World/NMS Group(1) is deleted
Minor	Location Engine	Configuration change: Floor /World/NMS Group(1) is added
  • Audit logs include:

Environment
  • ExtremeWireless
  • ExtremeManagement
  • All Controllers
  • EWC Version 8.32 and newer
  • XMC version 5 and newer
Cause
This can be caused by running two instances of XMC (EMC, OneView etc) that are managing the same controllers. The maps will continually synchronize to both management servers and controller, causing the plans to be added/deleted. 

Another cause of this can be shutting down a Windows, XMC server and creating a new Linux one and restoring the database from the Windows server. 
Resolution
To resolve this, and still run two instances of XMC, you can disable the map upload to one instance that is running.  To do this, navigate to Administration, Diagnostics, Map Server Details and select "Do not upload Maps:" 

User-added image

In regards to the problem with restore from Windows sever to Linux server, causing this issue, To resolve it we needed to go into each map, simply click edit then click save and the issue was resolved as it pushed all maps to both controllers and the error message stopped.
