Issue Description

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(77077f8)

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

Environment

What's the actual result?

openr will be killed by watchdog

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.
