Question
Why does the following log occur -

Answer

This log means that on the Interface specified, in the type of packet received from the corresponding Ipaddress, the checksum has failed. This could mean that the packet is corrupt.
For example, "OSPF Nbr Test receives type 2 pkt from 192.168.1.1 failed checksum" means that -
On Vlan interface "test" with neighbor IP 192.168.1.1, we have received a type 2 packet (DBD) that has failed checksum and could be corrupt.
