We analyse the measured critical current $I_{m\text{}}$ in a mesoscopic4-terminal S/N/S structure. The current through the S/N interface is shown toconsist not only of the Josephson component $I_{c}\sin \phi ,$ but also aphase-coherent part $I_{sg}\cos \phi $ of the subgap current. The current$I_{m}$ is determined by the both components $I_{c}$ and $I_{sg},$ and dependsin a nonmonotonic way on the voltage $V$ between superconductors and normalreservoirs reaching a maximum at $V\cong \Delta /e$. The obtained theoreticalresultas are in qualitative agreement with recent experimental data.Comment: 4 page, 3 figures. To be puplished in PRB Rapid co
