Hi Kaushik, I am unable to reproduce your problem with the code you provided on the latest build of deal.II and Trilinos.
- On how many processes did you run your program? - Did you use PETSc or Trilinos? - Could you try to build deal.II on the latest master branch? There is a chance that your issue has been solved upstream. Chances are high that fix #8860 <https://github.com/dealii/dealii/pull/8860> and the changes made to `get_interpolated_dof_values()` will solve your problem.
