These notification messages are normal when some changes in ARP table occur but when they can be noticed very often it can mean that there is some problem in the network like ARP attack or some other instability causing often changes in ARP table.
These messages are connected with addition and removal of some entries in ARP table what is resulting in removal or addition of appropriate entries in the routing of the VLAN interface in which changes in ARP table have occurred.
In normal network these messages can appear but if they appear very often on one specific interface it can mean that there is some problem with the network/devices attached to this interface or that there is some host attacking with some kind of ARP attacks.
