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.

Re: INTSTACK error

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.
