cphf solve2:SCF residual greater than 1d-2: What's this mean?

Just Got Here
I'm using NWChem 6.5 to run molecular properties calculations (I'm more interested in response).

I got a similar problem than Mark had, but in my case the output message was

--------------------------------------------------------------------------
 SCF residual:   4.755368962564806E-002
 ------------------------------------------------------------------------
 cphf_solve2:SCF residual greater than 1d-2                   0

  current input line :
    46: task dft property

The input that produces this is

Thanks in advance for any help.
