Sometimes FRR breaks down when there is a huge full table of routes

[liuxyon]

When I use Ubuntu 24.04 FRR10.2 and pfsense plus frr 9.2, I have a lot of upstreams pushing huge full-table routes to me. For example, when it reaches hundreds of millions of routes, FRR will crash. Sometimes FRR freezes, and sometimes it restarts. Are there any parameters that need to be adjusted and optimized? I have optimized some Ubuntu parameters to solve the problem of huge upstream full table routing. But there are still problems sometimes. Do you have any optimization suggestions?

Let us have a flamegraph when this is happening.

This is the pfsense freebsd15 system parameter. I have modified the parameters. Although it has improved a little, it still does not solve the fundamental problem.

I'll try installing it later.
