Rodney,
Apologies. Below is some output that I could get. I cannot get the interface configuration just yet, until the router gets reloaded, and I have put in a request for that.
Its very possible something bad is being done in the configuration, this router I have not been able to take a look at yet, I certainly didn't configure it in the first place.

When you post a question about a possible bug please always include the full IOS name.
That's because to decode the PC values we have to map it to a symbols file.
Can you post the relevant interface configurations also?
If you can get 'sh proc mem' to see what the process ID is for MLP bundle name then do a 'sh proc mem <PID>' for it.

Is anyone aware of any problems in 12.2.25S1 that would cause a memory leak in MLP?
We have a 7204 that is doing MLP on over 2 T1 lines, running 12.2.25S1 for about 4 weeks. It is out of memory so the CLI is not allowing me to do alot of things (like "show run").
I do see however:

I did check Bug Toolkit for anything that hit on MLP, but nothing in there looks like it would cause what I am seeing. The router is working, and I plan to reload it soon to do more diagnostics, but if anyone knows of this issue, please let me know.
