He was saying that a previous  runsp for this case conveges without problems.

So either the changes in optimize.job were wrong (dstart -up/dn missing?; complex
case, which needs -c ??) or the generated struct files are wrong
(diff the generated and original struct file. Do you have symmetry operations
set to zero ?, .....)
