Dear. Dr. Edoapra
  I recalculated this based on your input on macOS Sierra10.12.6 and Xcode8.3.3 
with NWCHEM6.6, and got
 sigma= .10D-02 eFermi= -0.17997 T*S= -3.27E-07 nel(1)=  190.00 nel(
d= 0,ls=0.0,diis 14 ... -1.76D-07 8.93D-06 2.16D-07 54.2

I think the calculations this time and last time perhaps both give unreliable results 
because using quick guess may not mean the stationary point is being aproached.
