we deploy Open/R on fat-tree，there are 8 aggregation switches and 32 edge switches, Open/R will occupy all memory of the device when the number of neighbors reaches 32, even though we have increased RSS memory to 800MB(https://github.com/facebook/openr/commit/77077f8de509ee5704014af65b3d435bc0e5ebe4)

what is the maximum number of neighbors that can be established?

Thanks for reaching out. Have you got a chance to leverage the latest main branch? Internally, we run the latest main branch, and it is possible to support more than 100 neighbors.
