Memory seems to grow endless

[Stéphane Bunel]

Hi,

Morning at 09:54 (GMT+2)

root at srtools:~# birdc
BIRD 1.2.4 ready.
bird> show memory
BIRD memory usage
Routing tables:     12 MB
Route attributes: 4592  B
Protocols:          34 kB
Total:              12 MB

Memory consumption has been multiplied by 480 in less than 24 hours.

I guess this is not a normal behavior isn't it ?

Regards,
Stéphane.
