[Pacemaker] Loss of ocf:pacemaker:ping target forces resources to restart?

I'd recommend adding more than one host to your p_ping resource and see if that improves the situation. When I had this problem, I observed better behavior after adding more than one IP to the list of hosts and changing the p_ping location constraint to be as follows:
location loc_run_on_most_connected g_mygroup \
        rule $id="loc_run_on_most_connected-rule" -inf: not_defined p_ping or p_ping lte 0

Hope this helps,
