Hotspot Lost DHCP Lease

Hello all,

We developed a authentication system integrated with MK API for hotels. The system was running fine until 2 weeks ago, when this problems starts to show up:
We`re running on a CRS125 for hotspot+dhcp, and the wifi system is a UniFi AC.

The problem is:
Sometimes when the client goes around roaming between the AP`s they loose their connection from the hotspot server ( it seems like the dhcp server cannot give the address so quickly ).

I`ve changed all parameters that are in my mind, any suggestions?

Regards.
