Hi,
when i look at the kernel messages i see lots of arp moved from logs like below

Code: 
kernel: arp: 0.0.0.0 moved from 00:ba:8b:04:c9:aa to 00:18:a9:7e:29:e3 on igb0
kernel: arp: 0.0.0.0 moved from 00:cd:14:0c:81:ca to 00:ac:a9:79:89:6d on igb0
kernel: arp: 0.0.0.0 moved from 00:fe:8b:04:c2:e5 to 00:ed:8b:04:c8:30 on igb0
so What could be causing this?
any help would be appreciated..
 
When some embedded devices start they send arp request before they obtain DHCP address using 0.0.0.0 which cause that conflict in the network. If you are the administrator of the network it's easy to locate on which port on the managed switch is this device and fix it.
