Hi Muru,

I would check the memory/cpu utilization and see if there anything that is eating the memory that you could free.

It looks like a bug and you may need to reboot your router.

Check this post. It might help you.

  Unless it free's up in a day or so the only fix for this is going to be to reload the box. It apparently has some sort of memory leak . Check for issues with your code release in bugtool.

It's a known memory leak bug.  You'll need to upgrade your IOS.
