Is there any error bar in frequency calculations using Gaussian09, suppose in DFT-B3LYP and 6-311+G(d) calculations?

In frequency calculations in Gaussian09 using DFT-B3LYP and 6-311+G(d) functional and basis set, we know that scaling factor is applied to correct the obtained frequencies. But is there any...
