  In this paper we prove a nonexistence result for nonlinear parabolic problems
with zero lower order term whose model is $$ \begin{cases}
  u_{t}- \Delta_p u+|u|^{q-1}u=\lambda & \text{in}\ (0,T)\times\Omega
  u(0,x)=0 & \text{in}\ \Omega,\\ u(t,x)=0 & \text{on}\
(0,T)\times\partial\Omega, \end{cases} $$ where $\Delta_p ={\rm div }(|\nabla
u|^{p-2}\nabla u)$ is the usual $p$-laplace operator, $\lambda$ is measure
concentrated on a set of zero parabolic $r$-capacity ($1<p<r$), and $q$ is
large enough.
