Ive have 3 standards and a full node.  they have all ran fine for quite awhile.  the full node and 1 standard are first batches and i have since upgraded the ssd.  like i said they have all ran fine for months.  one of the standards stopped and won't ever start back up.  i power it down and restart and it will go through the process but eventually it will just completely stop and stay that way.  tried restarting the whole thing numerous times as a reboot usually seems to fix any issues.  but not with this one standard unit.  any ideas?  thanks
