"have the server plugged into a smart plug with energy. I set it to power off between 23:04 and 23:15 only if the power levels dip below 5 watts for 2 minutes. After 5 minutes it powers back on. (Set the BIOS to always power on on power restoral)
unfortunately I have had to resort to similar. I do not have access to the beta firmware to adjust memory speed, I have 96gb mushkin memory, and server would crash every 2-3 days. I hooked up to a smart plug, and do a cronjob to backup all LXC's at 3:45 am, power down the node at 3:50, turn the power off at 3:55 and then power back on at 4:00 am.
works but id rather have a stable system.
