Some things to think about:

1. Make sure the gas tables are computed over the potential region of interest. There could be areas high/low pressure areas where the component properties are outside where the tables have been computed. Usually it would give you a different error in addition to above, but I have seen stranger things.
2. Another thing would be if you have a recirculation area with low pressure, you could, counterintutively, coarsen the mesh in this region. Now do this coarsening only if it isn't in an area where the solution critical. The reason the coarsing would work here is that it would artificially diffuse the low pressure region over a larger number of cells increasing the minimum value.
