Cisco Ethernet Interface keeps going admin-down same time each day.

Everyday, my Ethernet0 (cable modem interface) goes admin-down at 12:50:5x PM. I can't think what is causing this and not able to find any info on the internet (yet).
Thanks all!

I know this might sound like I'm paranoid but I would change your snmp string and create an access list for telneting in to your router. I really do't think this is the cause but from a security standpoint it is better anyway.
