INTSTACK error

I'm currently working with a Cisco 3800 as a part of my network. Over the passed couple of days, the router has locked up, the activity light staying a solid green, instead of blinking. When I attempted to console in, I received this error:

INTSTACK: Stack for level Network interfaces running low, 0/9000

If anyone could give me some clarification as to what this means, and also some reasons as to why a Cisco 3800 may be frequently locking up, I would greatly appreciate it. I'm currently in a learning process with Cisco routing. Thank you for your time.

Hi,

You should upgrade to 12.4(3j) as first step. If the message remains, more investigation would be needed. Currently, the bug database is down to search on it.
