Hi,

Why is that and How to stop 
 
ping 10.0.5.9

    How is the firewall learning the route to the destination network (10.0.5.9)?  Off hand, it looks like it could be a flapping route.  If it's dynamic look for messages relating to the routing protocol (BGP / OSPF) if static, make sure you are not seeing interface drops.
     
    When the ping is failing make sure you see the route in the Route Monitor or from the CLI type:
    get router info routing-table all
    - or - 
    get router info routing-table details 10.0.5.9
