Prior to upgrading to CentOS 7.4 everything was fine, after upgrade I'm seeing
/etc/keepalived# keepalived -f /etc/keepalived/keepalived.conf --dont-fork --log-console --log-detail --dump-conf -m -v
Starting VRRP child process, pid=17224 Registering Kernel netlink reflector Registering Kernel netlink command channel Registering gratuitous ARP shared channel Opening file '/etc/keepalived/keepalived.conf'. VRRP_Instance(VI_1) removing protocol VIPs. Keepalived_vrrp exited due to segmentation fault (SIGSEGV). Please report a bug at https://github.com/acassen/keepalived/issues and include this log from when keepalived started, what happened immediately before the crash, and your configuration file.
KLeepalived just respawns, segfaults, respawns ...
Someone else has reported a similar issue, https://github.com/acassen/keepalived/issues/650
