OSPF checksum error on Cisco

I have a PM2e running ComOS 3.5.1b17 on a 10baseT Ethernet with a Cisco
2501. For some reason lately I have been getting this syslog error every
ten seconds from the Cisco:

Jul 12 17:10:48 eth0-router0.Gallup.cia-g.com 1740: Jul 12 17:10:47:
%OSPF-4-ERRRCV: Received invalid packet: Bad Checksum from 206.206.162.3,
Ethernet0

A few days ago the ethernet wires between both devices were replaced
because the others weren't made very well in the first place. That fixed
it so that both devices become OSPF neighbors and exchange routes now.
They didn't previously.

But the problem continues, any ideas what could be causing this? All
other communications work without problems between the devices.

I have PM2e's and Cisco's on other ethernets communicating with no
problems. Also the Cisco 2501 above is speakign to GateD without
problems.

Thanks.
