Core Issue
A software-forced crash occurs when the router detects a severe, unrecoverable error and reloads itself to prevent the sending of corrupted data. A vast majority of software-forced crashes are caused by Cisco IOS Software bugs, although some platforms, such as the old Cisco 4000, may report a hardware problem as a software-forced crash.
Resolution
If you have the output of a show stacks or show tech-support command from your Cisco device, you can use the Output Interpreter to display potential issues and fixes.
For more information on how to address this type of issue, refer to Troubleshooting Software-forced Crashes.
