  The problem of a spin-1/2 magnetic impurity near an antiferromagnetic
transition of the host lattice is solved. The problem is shown to transform to
a multichannel problem. A variety of fixed points is discovered asymptotically
near the AFM-critical point. Among these is a new variety of stable fixed point
of a multichannel Kondo problem which does not require channel isotropy. At
this point Kondo screening disappears but coupling to spin-fluctuations
remains. Besides its intrinsic interest, the problem is an essential ingredient
in the problem of quantum critical points in heavy-fermions.
