Hello, I installed different version of bird on Ubuntu 16.04 (namely, 1.5.0, 1.6.3, 1.6.4). After leaving the daemon running for ~1 hour, the memory used by the host is over 8Gib. However, when running `birdc show memory`, I get the following: BIRD memory usage Routing tables: 21 kB Route attributes: 11 kB ROA tables: 192 B Protocols: 22 kB Total: 102 kB My config is pretty basic (edited, see attached) as we have 2 BGP protocols using 2 ASN (one public, one private), each exporting the routes learnt from the other. The leak seems to be related to the traffic going through the server, as the memory of the host remains still when there is no traffic going on. It is triggered by bird though, because I don't have the leak when the routes are configured statically and bird is shut down. The weird thing about this is that the memory is not used by the bird process itself. It's shown as used memory by the host, but no process is actually using this memory. I know that it's leaking because of bird though because it's the only process installed and running on this host. Has anyone ever encountered such a behavior, or can see an issue in my configuration? Thanks in advance for your help -- Willy
