How do you trouble shoot this problem, I've got a couple of L3 4500's and a couple of 7200's for VPN tunnels

Hi
Stuck in active means the router/L3 switch is actively qureying neighbors for a route to 10.0.0.0/8 but is not getting replies from all neighbors.
Check for congested links which would delay the responses or a router under a very high CPU load which again coudl delay a response.
Also have a look at this link

I's just this one route that the switches are complaining about
Etherchannel between the two 4500's,
Multiple Vlans between the Switches that they are neighboring on

Hi
Okay, it would be a good idea to read the attached link. From your output above
via 10.11.1.2 (Infinity/Infinity), r, Vlan11, serno 5549635
The same , r, means USL3ATL002 is still waiting on a reply from 10.11.1.2.
So you need to look at 10.11.1.2.

This is the some output from the other 4500
Low processer utilization low bandwidth usage

Why is it only this one route that the switches are complaining about?
Is this static route 10.0.0.0 with a metric 200 messing up the routing?
