I am trying to perform pseudo surface with adsorbed molecule optimization with smearing, similar to the example in the plane wave section but it aborts with this cryptic error. My error is below, suggestiosn how to solve this particular error and improve my setup of calculating adsorbed molecules on surfaces would be appreciated

I get a similar error with fermi smearing: Pneb_w_diag: ZHEEV failed 19.
When I run a job with an identical input file but without the line "smear fermi", I don't get an error, but when I include the line "smear fermi", I get the error message above. The end of the output file says:
fractional smearing parameters:
smearing algorithm = Fermi-Dirac
smearing parameter = 0.100E-02 ( 315.8 K)
