[Moose-dev] Error exporting big models

Hi I'm trying to do some benchmarks using MSE import and export, and for that I am using MooseScripts to create test models. But many of them (I think the bigger ones) I get an error. I am attaching an screenshot, maybe is useful. For reproduce it in a new Moose 4.1 "one-click", I do: MooseScripts createModelForMorphic. And then, in a MoosePanel I click on Export to MSE, and after some seconds I get the error. Should I report a bug in the issue tracker? Does somebody know the cause of the error? Thanks in advance, Martin
