Lots of stuff merged between 384a885111ad and 2cbd132986a7. Thomas, is it possible for you to work more on isolating the regression? Things to check: 1) Did bird upgrade 2.0.9 to 2.14 switch bird to use NETLINK instead of route socket? If 1) is false, there are two options: 2.0.9 and 2.14 both used NETLINK or both used route socket. If the latter, than my guess is totally wrong and Mark's guess is much better. If the former, than we need to bisect between 384a885111ad and 2cbd132986a7. 2) If 1) is true, then please compile 2.14 with NETLINK disabled and check if leak has gone. If 1) and 2) are true it could be the problem was in 384a885111ad as well, but you did not use NETLINK. 3) Check if running with NETLINK on 384a885111ad reproduces the leak or not? (Be careful, as lots of bugs were removed after 384a885111ad) Depending on 3) we may need to run bisection. Anyway, please keep us updated when you got more info, starting with 1). --=20 You are receiving this mail because: You are the assignee for the bug.=
