MJDGGES error codes

Greetings,
I am working on a project and have run up against a strange problem. When I run my mod file on a Windows machine with Dynare 4.2.1 installed, it works fine. When I run the same mod file on a Mac or a Linux box, I get the following message:

MJDGGES returns the following error code: 459

I cannot seem to find anything indicating what this code might mean. Any help would be much appreciated.

Most likely there is a singularity in your model that is caught under Mac/Linux but not under Windows. You must be very close to the critical value.
Please, post or send me your *.mod file and I will confirm.

Best

Michel
