incorrect memory usage reporting

[Job Snijders]

Hi all,

I use a BIRD instance for route collection from ~ 50 full bgp feeds [1]. The
'show mem' command reports very ambitious results:

    job at lg01:~$ sudo birdc show mem
    BIRD 1.4.2 ready.
    BIRD memory usage
    Routing tables:   4294967294 GB
    Route attributes: 1540 MB
    ROA tables:        192  B
    Protocols:         311 kB
    Total:               0 GB
    job at lg01:~$ free -m
                 total       used       free     shared    buffers     cached
    Mem:          8759       4944       3815          0        187        366
    -/+ buffers/cache:       4390       4369
    Swap:          486          0        486
    job at lg01:~$

Might there be a counter that wraps around? How can I help debug this?

Kind regards,

Job
