GPOS error when exporting variable font

I searched for similar issues in the forum but did not find any solutions.

I have an issue when I’m trying to export a variable font (ttf) that says :

Problem compiling “GPOS” table
Subtable Overflow in lookup: 2 type: PairAdjustment

I have 496 glyphs and 9087 kerning entries.
I’m surprised because it was working earlier and now it is failing.

Thank you for your time!

Thanks to @FlorianPircher I just found a way around the issue:

Merci !

I don’t know your design, but 9000 kerning pairs sound quite a lot. You might need to improve your spacing before you start kerning. And do you use groups/classes?
