Packet limit 800pks/sec exceed message after upgrading to ControlBuilder 6
Is there any system variable that I should adjust? Or any other parameter?

This is the works of the AC 800M storm filter protection which was introduced in 800xA v5.1.
To avoid CPU overload and potential intentional controller reset if CPU load is too high, the controller will disable its Ethernet interfaces when the threshold is reached (800 packets/second, some controllers allow more).
The limits are hardcoded and cannot be adjusted, nor disabled.
Please read more about the storm protection in the user's guides - see also this Technical Description on ABB Library (ABB intranet access or subscription required).
800 packets per second is a lot, is there a fault in the network? Are you using a hub to connect the controller instead of a switch?
