yes , you could have an issue with routes external to your as that are being redistributed into your AS , EIGRP only uses a RID with routes that are tagged with an external AS , If you have a network that is advertised to By a router that has the same RID as you , your router will ignore this update because it assumes that it is being advertised by himself.
You must have two eigrp routers with the same router id.... Generally this happens because two routers have the same interface ip addresses, or you've moved an ip address from one router to another. First, check for duplicate ip addresses on the router doing redistribution and the router putting this message out, renumbering as needed, and then restart the eigrp processes on the two routers.
A sh ip eigrp events will show you the subnets that are being ignored , you will also be able to track down the router with the dup RID , I have found that this happens most often when the loopback of a router gets changed , Eigrp will keep the original RID , to correct this you must remove & replace the proces or the cleanest way is to relaod the box eith the bogus RID. A sh ip eigrp topology will tell you the RID
