Bird 2.0.0 memory leak

[Miłosz Oller]

Hi

After bird starts:

bird> show memory
BIRD memory usage
Routing tables:    598 MB
Route attributes:  161 MB
Protocols:         306 kB
Total:             759 MB


After next ~5mins:

bird> show memory
BIRD memory usage
Routing tables:   1534 MB
Route attributes:  161 MB
Protocols:         306 kB
Total:            1696 MB


Config with 17 sessions and one iBGP:

one of sessions:

protocol bgp bgp_atm_pl_backup {
     description "ATM Peering.PL Backup";
#    import all;
ipv4 { import all; };
ipv6 { import all; };
     ipv4 { export filter ipv4_export; };
     local as 198611;
     neighbor 212.91.2.1 as 24748;
     source address 212.91.1.42;
#    default bgp_local_pref 110;
}
