I tried to plot the DOS for Silicon, using an FCC cell at zero pressure. I used both ISMEAR=0 with SIGMA=0.01 and ISMEAR=-5. The results are very similar, and it seems that Si is a metal (!). There is no visible gap anywhere...
Any ideas what I'm doing wrong? I tried with v.4.6.13 and 4.6.28 with the same results.

fcc Si has no gap whereas the ground state diamond structure of Si has please look at the vasp workshop files, handsonII.pdf, pps 11 and 15) .
