Description | This article describes how to deal with a kernel panic. |
Scope | All versions of FortiOS. |
Solution |
A kernel panic is an issue that occurs when the kernel cannot handle operations and the system shuts down or reboots.
To diagnose the cause of the kernel panic, collect the information outlined by this article when it occurs and send the debug output to the support team for investigation. See the instructions below.
Important note:
Note:
If Multi-VDOM mode is enabled on FortiGate, navigate to the GLOBAL VDOM and then execute the commands as outlined below:
config global
diagnose debug console timestamp enable
diagnose debug kernel level 8
diagnose debug duration 0
diagnose sys nmi-watchdog enable diagnose debug comlog enable diagnose debug app ipmc -1 diagnose debug enable diagnose sys top 280
diag sys top should keep the session active automatically.
Use monitoring tools for system outages.
Gather the crashlog and the debug log: diagnose debug crashlog read diagnose debug comlog read
Gather system event logs. If the system is a cluster, gather the logs from all nodes.
diagnose debug comlog disable diagnose debug comlog clear |
