MikroTik

Hi guys!
I need some help..
Can someone tell's me why am i having problems with interface that is generating in average 70mbit traffic without any reason.. To explain problem in simplest way, let's say that i have two mikrotik routers that are connected with each other by cable.. Yesterday, that interface on both sides that connects that two routers is generating 70 mbit traffic when no one else is on the network.. and i mean in both directions...
why is this happening? anyone?

thx!

check "tool torch" to see where it is coming from

i already did that but nothing. Didin't find any ip that is consuming that much bandwidth.. The interface is generating way to much...

maybe routing loop?..

Removing static routes when neighbour router wasn't reachable helped. Neighbour router coming up, enable routes, everything OK.
