How much RAM for Full Internet tables

[James Swineson]

I wonder if your bird (or other program) is leaking memory. Here's my bird receiving v4 and v6 near-full table and doing some filtering:

bird> show route table global_v4 count
806364 of 806364 routes for 806364 networks in table global_v4
bird> show route table global_v6 count
89509 of 89509 routes for 89509 networks in table global_v6

This is a 1G RAM VPS, bird virtual memory usage is <400M.
