When it crashed, apparenlty it was the end of the run where the program needs to deliver all the outputs. As far as I know the freeze problem was only linked to variances and not fixed effects (you have a freeze fixed effect too). Therefore I think this crash should not show up.
If it is agin then we will deal with it.What engine are you using for optimization (FOCE ELS, QRPEM,?)
