iptables messages

I'm getting quite a few messages in my logs from itables. There seems to be a problem with packets coming from the primary DNS (10.1.1.5). The messages look like this (this is output from logwatch):

   From 10.1.1.5 - 334 packets
      To 10.1.5.93 - 334 packets
         Service: 32972 (udp/32972) (INPUT packet died:,eth0,none) - 1 packet
         Service: 32973 (udp/32973) (INPUT packet died:,eth0,none) - 1 packet
         Service: 32974 (udp/32974) (INPUT packet died:,eth0,none) - 1 packet
         Service: 33063 (udp/33063) (INPUT packet died:,eth0,none) - 1 packet
         Service: 33112 (udp/33112) (INPUT packet died:,eth0,none) - 1 packet

I *believe* that dns is working properly on this box (10.1.5.93). For example, reverse lookups work when I ssh into it. Could someone tell me why I'm getting these messages? Is the DNS misconfigured?

Oh, I'm running RHEL ES4 on this box. Don't know what the DNS box is running.

Thanks!
