The 4sigma=360 (or 4nu=1) resonance of a linac is manifested when the depressed tune sigma is close to and below 90 . It is observed that this fourth order resonance is dominating over the better known envelope instability and practically replacing it. Simulation study shows a clear emittance growth by this resonance and its stopband. Experimental measurement of the stopband of this resonance was proposed and conducted in 2008 using the GSI UNILAC confirming this resonance. The result is presented at a separate paper in this conference
