Breaking all wall in Graff Mines is interrupted over and over

Breaking Wall (all walls at least the two I have found) in Graff Mines is being interrupted over and over. There is no monster to cause the interruption. One must click all over the area once the curser is green it starts the break wall process but then a message pops up and says it is interrupted. I relog into the scene and it happens over again. I can finally get the wall to break but only after many attempts often then being interrupted by a Kobald or Skeleton.
