Narrative:

During struck six arrival for hou my aircraft was cleared direct to the tnv VOR. While passing over tnv VOR ATC reported a lack of sep between my aircraft and another aircraft. We were asked to make an instant level off, which we did. DME and VOR bearing in my aircraft indicated we were within two mi of course centerline.
