Content Router dns keepalives

I am having an unusual problem between my content router and content engines. Right now I have a basic configuration of 3 machines: CDM(cdm4650-5.0.1), CR( ce565-5.1.5), CE( ce565-5.1.5). All three items are plugged into the same switch. All machines are seen by my CDM gui. My problem is that my CR does not register my CE. When I do " show statistics content-routing dns" I see that the CR has received 22744 keepalives:

#show statistics content-routing dns

----- CR DNS Statistics -----

Total DNS queries : 0

Web site FQDNs : 0

Content engine aliases : 0

Aliases for Down CEs : 0

Unknown domains : 0

PTR queries : 0

Failed : 0

Dropped : 0

Content engine keepalives : 22744

From unknown source : 6

However when I do "show statistics content-routing ce" the CR reports that the CE has sent no keepalives. I only have one CE so I know the keep alives are coming from it. In fact, I can do a "tcpdump port 53" and see the ip address of my CE sending the dns keepalives.

#show statistics content-routing ce

----- Statistics Of CE: "EUSTROOTCE-CE" -----

IP Address : 0.0.0.0

Aliveness : down

HTTP 302 Redirects : 0

ASX Redirects : 0

RTSP Redirects : 0

Number Of Keepalives : 0

Has anyone had an issues like this when setting up their CDN?

Are you using 10 Mbps connections to the switch. If so there is a known issue with some versions of the CE where it only registers as half-duplex because the line speed autosense detection of the network adapter card fails to determine this setting correctly.
