I am getting this error when solving a poisson equation discretized with hp-FEM and Lagrange basis functions.
The solver is CG.
Any idea what could that be?
p.s. the error appears only for a very particular combination of h and p refinement,
perhaps it could be related to a particularly bad condition number of the matrix?
