[Keepalived] Memory Leak ?
Open, Requires assessmentPublic

Description

Hi,
I've 2 VRRP group. One for each interface off my node.

adminsib@vpn-front01-a.sib.fr# run show vrrp
Name                     Interface      VRID  State    Last Transition
-----------------------  -----------  ------  -------  -----------------
vpnfront-vrrp-interco    eth1             10  MASTER   4d2h19m10s
vpnfront-vrrp-intercoFW  eth0             20  MASTER   4d2h19m10s
[edit]

since the VRRP was implemented wee see that every 2/3 day, there is a node switchover

We can see that in /var/log/messages :

Jun 21 00:17:50 vpn-front01-a kernel: [659082.424326] Out of memory: Kill process 2002 (keepalived) score 605 or sacrifice child
Jun 21 00:17:50 vpn-front01-a kernel: [659082.427243] Killed process 2002 (keepalived) total-vm:691972kB, anon-rss:612568kB, file-rss:64kB, shmem-rss:0kB

We also note that Vyos consumes 80MB more per day

I think than when keepalived consumes a lot off memory, and memory is full, Vyos kill one of two keepalived process
