We need a more information than that to diagnose. Is this at the very beginning or later in the protocol? Can you post more of the log?
You should have seen a nearby line like "ERROR: Could not find disulfide partner for residue ###", listing a problematic residue number where Rosetta was confused about its disulfide status or disulfide partner. (This is in "rosetta numbering" rather than chothia, so it will be all residues numbered sequentially from 1, not restarting with each chain.) What residue is that, and was there anything strange about it in the input?
