Not for first time i am facing an issue where, if i play a little bit with specific device moving it from zone to zone and changing it's ip address, there come a moment that i get IP conflict even if the IP doesn't exist in netxms. To be more specific, here is example scenario.

lets say i have two zone 3 and 33, and one device with management IP of 10.10.10.10 and Public IP of 100.100.100.100.

I am adding it to zone 3 with the public address, then changing it to the private one. Next i am changing the zone to 33 (the device is still with the private address), setting back the public IP address is okay. If i move it back to zone 3 i will get IP conflict with the exact same device, but it really doesn't exist in console (for zone 3 anymore). I checked the database directly from the machine and there is no entry for this IP address, unfortunately i get the error.
If i check the address map of the zone i can see that the IP is used, but for sure the device doesn't exist with this ip anymore.

After a while (1-2 hours or even more in some cases) the device/IPaddress disappear  from the address map of the zone and it is vacant again.

Is this normal? How can i avoid this ?

Best regards,
Adrian
