Check the Routing Engine Core Files
Purpose
If you observe disruption to the Routing Engine kernel, check the /var/crash directory for any core files created around the time of the crash.
Action
To check the /var/crash directory, use the following Junos OS command-line interface (CLI) operational mode command:
user@host> file list detail /var/crash
Sample Output
user@host> file list detail /var/crash total 1577912 drwxr-x--- 2 root wheel 512 Sep 9 11:59 ./ drwxr-xr-x 22 root wheel 512 Oct 29 2001 ../ -rw-r--r-- 1 root wheel 2 Jul 20 01:11 bounds -rw-r--r-- 1 root wheel 2166913 Jul 20 01:11 kernel.0 -rw-r--r-- 1 root wheel 5 Feb 15 2002 minfree -rw------- 1 root wheel 805306368 Jul 20 01:11 vmcore.0
Meaning
The sample output lists the contents of the /var/crash/ directory. Check the date and timestamp for any kernel core files created around the time of the crash. In the example above, two core files are listed: kernel.0 and vmcore.0.
