I did open this as case 600867998 and put the configs in place.

Possibly CSCsa49019, which is committed to 12.2S, but not yet integrated into a release. Would need to see the configuration first to make sure. "debug ppp multilink events" should generate some error too if you are running into this problem. Is the bundle up and running?

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.
