autosupout.rif

When is a autosupout.rif file generated? I have a few routerboards that will generate autosupout files every now and then, but everything is working fine. Should I be concerned?

System watchdog feature reboot the system in case of software failures.

Pl check
/system watchdog

automatic-supout (yes | no; default: yes) - when software failure happens, a file named “autosupout.rif” is generated automatically. The previous “autosupout.rif” file is renamed to “autosupout.old.rif”
