Collect Crash Data for a Routing Engine Kernel
Purpose
When a Routing Engine kernel crashes, the Routing Engine automatically reboots. By default, the Juniper Networks router does not attempt to dump a core if the Routing Engine kernel crashes. As a result, there is no crash data on the router to help investigate the crash. In addition, the system log messages are similar to those generated when the router is powered down and restarted, so you cannot tell if the Routing Engine restart was caused by a kernel crash or a normal power restart.
Steps To Take
To collect crash data for a Routing Engine kernel crash, follow these steps:
