I'm almost sure these commands (right or wrong) can trigger such a leak:

$ sudo tc qdisc add dev lo root handle 1: htb
$ sudo tc filter add dev lo proto ip pref 1 handle 800::1 u32 match u32 0 0 classid 1:1
$ sudo tc filter add dev lo proto ip pref 2 handle 800::1 u32 match u32 0 0 classid 1:1
RTNETLINK answers: File exists
