@amontoison Ah I was sure I replied.
You were correct. Using rtol=0.0 fixed it. It seems like I was misunderstanding the meaning of rtol.

Hi @alexQueue!
GMRES should stop when ||r_k|| <= atol + rtol * ||r_0||.
The initial residual r_0 is b.
You can set rtol=0.0 in your case.
I still don't understand why GMRES stops before that ||r_k|| <= 1.9 * 1e-5 is reached.
Can you save and share your linear system with MatrixMarket.jl?
