That's an Address Resolution Protocol (ARP) packet. The machine with an IP address of 10.248.252.50 wants to send a packet to the machine with an IP address of 169.254.25.31, and believes that machine is on the same network as it, so it's sending a broadcast packet on the network in the hopes of getting back a packet giving the MAC address (such as an Ethernet address) for that machine.

169.254.0.0/16 is the APIPA range. How can a system with 10.248.252.50 believe it is in the same subnet? That would be only possible with a netmask of /0 (which does not make any sense)!?

@dbruce: Please check the configuration of the system 10.248.252.50.
