Unrecoverable System Restarts
An unrecoverable system restart might occur in the following cases:
•
A critical process fails and is not restartable.
•
A process restarts more times than is allowed by the system configuration.
•
A process restarts more frequently than is allowed by the system configuration.
The effect of a process reset is determined by the policy configured for each process. An unrecoverable reset
might cause functionality loss, the active supervisor to restart, a supervisor switchover, or the system to restart.
The show system reset-reason command displays the following information:
•
The last four reset-reason codes for a specific module in a given slot. If a module is absent, the reset-reason
codes for that module are not displayed.
•
The overall history of when and why expected and unexpected reloads occur.
•
The time stamp of when the reset or reload occurred.
•
The reason for the reset or reload of a module.
•
The service that caused the reset or reload (not always available).
•
The software version that was running at the time of the reset or reload.
