Contact Quad support at systems-support@viewlogic.com, and try modifying
the
XFX configuration by slightly changing some of the dimensions in the
.xfx file.

Make the trace width 5.001 instead of 5.0, etc.

Sometimes a slight change will avoid some instability in the calculation
engine. Send the config to quad support, so that they know there's a
problem. This is XFX, not XFX3D, right?
