i'm getting these lines in my switch log and i'm not sure whether to be worried about or what?

034389: Mar 30 02:28:25 central: IP-EIGRP(Default-IP-Routing-Table:100): Neighbor 10.30.13.10 not on common subnet for Vlan306
034390: Mar 30 02:30:46 central: IP-EIGRP(Default-IP-Routing-Table:100): Neighbor 10.30.13.10 not on common subnet for Vlan306

Thanks

It means that there are 2 EIGRP neigbors on vlan 306 but they have been configured with a different IP/subnet mask. Check the IP address and subnet of every interface on the L3 switches/routers that connect to vlan 306.
