ASG120 stops functioning sometimes after upgrade to UTM9

Hi,

don't know if it's related or not, but since our ASG120 was updated to UTM9 every now and then it stops routing traffic. The web interface is still accessible. I have to reboot the unit in order to have it operational again.

The kernel log reports:
