Assume that is a bounded domain in with , which satisfies a uniform interior and exterior cone condition. We determine uniform a priori lower and upper bounds for the growth of solutions and their gradients, of the problem with boundary blow-up, where or with . The boundary estimates imply existence and uniqueness of a solution of the above problem. For with the solution is positive. These results are used to construct a solution of the problem when is the von Koch snowflake domain.
