Hello! I imagine why files listed below have 666 file mode bits set: /var/run/checkers.pid /var/run/vrrp.pid /var/run/keepalived.pid /var/run/starter.pid /var/lock/subsys/ipsecFiles are created during startup of ipsec (pluto) and keepalived deamons.
I think thar leaving them world writable is security hole. For example delete or change of its content could confuses monit watching them running and restarting when they die.
