Hello,
I'm unfortunately not able to reproduce this bug.
However, I had to reduce the mesh size...
Do you have the same problem with a coarser mesh?
Do you know which library GetDP uses for the eigenproblem (Arpack or SLPEc)?
If you don't know, can you rerun your example with the -slepc argument?
By the way, the spectral shift is a bit low (-1).
In my test, I used EigenSolve[w,10,-1e6,0].
I get a fundamental mode around 130Hz.
