BIRD memory usage

[Alexander Frolkin]

Hello,

We are running BIRD on a number of servers.  It is configured with two BGP
peers.

We are seeing BIRD using over a gig of memory, and this seems excessive,
especially given the number of routes.

BIRD 1.5.0 ready.
bird> show memory 
BIRD memory usage
Routing tables:   1142 MB
Route attributes:   48 kB
ROA tables:        192  B
Protocols:          45 kB
Total:            1142 MB
bird> show route count
656 of 656 routes for 333 networks

The memory usage goes up slowly, starting from a few MB; this particular
instance has been up for 3 days and 2 hours.

Is there something we can do to reduce the memory usage?  Or could this
be a memory leak bug?

The config is attached.  Let me know if you need any more information.

Thanks in advance!
