Why does try-catch command fail sometime?

I have been using try-catch command in my loop for solving economic model using Dynare. It does the job normally, but sometimes it doesn’t. For example, the following error happens all the time, and the try-catch command catches the error and moves on to next iteration. But yesterday, it stops the whole program.

'Blanchard Kahn conditions are not satisfied: indeterminacy.

the code I am using is:
dynare US_EAcoordination;
catch err
load file_name;
tem_iteration = strcat(‘iteration_’,num2str(iteration));
estimation.(char(tem_iteration)).errmag = err.message;

Thanks so much.

Are you using Matlab or Octave. Which Dynare version? Can you replicate the error? If yes, please send me the mod-file.
