What could cause this to happen? The ethernet port is broadcasting to all IP's constantly.
Please advise.

Please upload your config.

Does your config have a line that says:
service config
This will cause the router to try and find a TFTP server to download configuration files from. Remove that line and it will stop.

No such line exist.

Richard,
We'll need more information in order to assit you with this problem. Cabn you post the router's config?

The fist thing I noticed is that your acls need to be changed
currently you have these as your final three lines:
access-list 101 permit ip any any
access-list 101 permit tcp m.n.p.0 0.0.0.255 eq telnet any
access-list 101 deny tcp any any eq telnet
Once a packet hits the permit any any statement, no other lines will be processed. Just a quick housekeeping note.
Are you using a sniffer to identify the broadcasts? How frequent are the broadcasts? I need a little more information about the broadcast to help you. I don't see anything in the config that would create broadcasts.

Yes. Quite frequently as a matter of fact. We are suspecting a defective component. How can this be verified?

What are the broadcasts? What is the destination address? What does the packet contain? What information can you provide regarding the broadcast? I can only guess at what the broadcast is unless you provide more information via a sniffer or using netmon...
