List the Core Files Generated After A Crash Occurs

A vmcore file is only generated if the Routing Engine has a kernel crash. Kernel crashes can be generated by such things as a bug in the kernel software or bad memory. If the router has a kernel crash, the vmcore.<n> file is generated while the Routing Engine comes back up.

Action

A vmcore file is always saved in /var/crash/. To view the core file that is generated when a crash occurs, use the following CLI command:

user@host> file list /var/crash/ detail 

Sample Output

user@host> file list /var/crash/ detail
