I've had intermittent issues with an ERL and random reboots. Until recently, I've not been able to capture serial console output as I didn't have the correct cabling, but this has since been remedied. I've finally been able to capture one of these events. The log is attached below -- any ideas how to further diagnose/correct this?
Thanks,
John
