vMMAC_SetChannel() throwing WATCHDOG exception

I'm using a JN5168 module running Contiki and I've currently an issue where I change the channel quite frequently and sometimes it gets stuck when calling vMMAC_SetChannel() and it throws a WATCHDOG exception and reboots. Can anyone help me with this problem? The watchdog timer value is set to its maximum value of 16392ms. I'm using the latest SDK "JN-SW-4163, Build 1416".
