I also get this, for instance when adding a capacitor of sufficient value to a simple bridge rectifier when the ground is on the low side of the AC supply. It simulates fine for low capacitance, but when I increase (in a reasonable range) it fails to converge.
When I move the ground to the low side of the rectifier bridge it simulates fine, with any capacitor value.
