    Unless the target is running on super old hardware, there should be a TCP Offload Engine (TOE) on the NIC that should be handling things like ping responses without consulting the kernel: meaning that it's not likely due to the target. 

    Yes, I'd suspect the network first. In addition to Mike's questions: are there any firewalls (adaptive/dynamic ones) between the collector and the server? Is it possible you have an IP address conflict on the network?
