FortiWifi 30D freeze

Hi guys,

I'm having some issues in 3 FortiWifi 30D installed in different clients.

When we enable local Wifi, and a few clients (About 4) connect to wifi, the firewall freeze, only back to normal after reboot the device.

I know that is the problem because I disable Local Wifi and this issue stop happen. In other case I disable Local wifi and enable a FortiAP, then no freeze.

All of them the partnumber is P14766-02.

Does anyone is having this issue ou something related to this?
