Bugreport: Traffic flow hangs device if enabled on beta 8/be

If Traffic flow enabled, it hangs router in 5-10 minutes (with no comments in screen or logs).

When trying to add traffic flow target with Winbox, i get error:
“Error in address - network flow expected!”
…no matter what ip:port I enter.

and.. if i stil want to do anything, i enter the terminal and add traffic flow target there… but. no data reaches machine with Ntop. (it worked with ROS 2.9).

Mikrotik is running on 3.0 P4 (HT enabled), supermicro p8sct, kingston 1gb ram 667 non-ECC, Transcend 128mb ide-flash and working with ~40 mbps (10 000 pkts/s ) traffic, throught 4 bgp peers ( 2 full tables, and 2 ~400 routes). cpu usage 12-17%, ram ~250 mb.
