Endian network crash

Hi,

I have this strange problem that have happened two different nights in a row. Endian stops networking. In firewall log I can see this:

BADTCP:DROP TCP (br0) 172.16.3.52:53293 -> ...:80 (eth0)

For any connection that I try to make over the firewall. In any other log there is no trace of problem. Also I can't ping or access web interface. Problem is resolved when I restart the firewall.

Endian is on Hyper-V and there is no error messages in Event Viewer. However I did notice about 1 hour before the networking stops endian's CPU usage and bandwith goes unsually high and stays there until the crash.

Any help would help to solve this.
