PRO 6 locking up

I have a pro 6 with a 9tb volume and a 6tb volume. About once a week, the whole drive drops off the network and can't be accessed through CIFS or the web admin interface. It doesn't turn off, the light on the power button is still on and the fan is still going, but it basically acts like it's off. When I press the power button on the unit, nothing displays on the LCD panel as it does when the unit is working properly. When I press and hold the power button to power off and then power back on, everything is working fine again.

Any ideas on what would be causing this and how I can fix it? It's a big problem because the only way to refresh the system when it's locked like this is a manual physical reboot, which I obviously can't do when I'm trying to access it remotely.

There are issues to certain versions of Linux overallocating memory to requesting processes. This can be fixed by setting the following values in /etc/sysctl.conf. The reference article in the comment listed below explains what is happening, why, and how to resolve it.

vm.overcommit_memory = 2
vm.overcommit_ratio = 80

My Pro started doing that a little bit before the power supply gave out entirely. That's not necessarily it, I'm sure there are other things that can do it, but be on the alert. If it starts not booting all the way sometimes, then that's the real key that the power supply is likely on its last legs.
