ipv6 routing memory leak


Is it possible to bug is in debian 7?

im running debian 7.11 with kernel 3.2.0-4-amd64 #1 SMP Debian 3.2.84-1 x86_64 GNU/Linux

and on several machines debian 7 ipv6 stops  working after a while so i started to investigate the issue.

wc -l /proc/net/ipv6_route
25329 /proc/net/ipv6_route and its still growing every minute.
once i reboot the machine ipv6 works again for 1/2 days

on another machine (debian jessie)
i checked the same value and it shows me:

wc -l /proc/net/ipv6_route
107 /proc/net/ipv6_route

so in jessie im not having this issue

both machine are identical in setup settings sysctl etc

it looks like that on debian 7 its not releasing its memory

i have around 50 machines on debian 7 and they are all having this issue.

KInd regards.
