Does the GLB_RT_OVERFLOW_ITERS setting in the OpenLANE manual work correctly? In my environment, no matter what value I set it to, the iteration stops after 50 iterations. https://openlane.readthedocs.io/en/latest/configuration/README.html#routing

I think 50 is MAX value as per industry standard. Tool will run GRT till overflow comes down to 0 till given iteration level else stop with error.
Try change your value in configuration/routing.tcl
