Likely the solver has failed to find an optimal solution in that case. Or it could also be some GAMS error. In any case, looking at the listing file (*.lst) should reveal the cause, and possible approach for cure. Maybe you can post it (zipped)?

Thank you for your response. I checked for the LST file and from there I got a clue to check for the QC file. Finally, I get a hold on the problem. The issues occurred due to addition of unnecessary time slices by AnswerTIMES (this sometimes happens when we use the excel import feature) in one of the country model. I remember this happening sometimes back too when I used the excel import feature but it slipped my mind.
