Where's the crash dump file?

Hi - I’ve been having some random crashes on my new asterisk (a@h) install. Does anyone know where the kernel dump file is located so I can investigate further?

Thanks.

you can type dmesg or you go to /var/log/asterisk

Is this the asterisk dump file? If so, it’s the kernel dump I’m looking for.

Also – is there a way to set asterisk a@h to reboot automatically after a crash? Most of the time it crashes I am stuck without remote access. Would be better if it could reboot automatically.
