Hi

I would like to confirm, it is BIRD that was killed by out of memory
killer and could be just restarted? Or Linux kernel crashed? (You wrote
'the kernel crashed with out of memory issue' in one prior mail.)

In the first case, how much memory BIRD takes after start and before it crashes?
How long it takes to crash to crash due to OOM?

It is likely related to 64 path BGP multipath exported to kernel.
