Your SCF (ie the electronic density) has not converged, this can be due to a number of sources, some things to check and or try are:

if this is one of the first few steps of an optimisation, check your geometry, are any atoms too close together?
if this is restart from a checkpoint file, start the job again, but this time avoid reading in any information from the checkpoint file. If the job doesn't fail it means some of the updating got a bit out of wack or your checkpoint file was the wrong one, or it became corrupted or ... If the job fails again then you have a more serious issue.
