Hub is running low on memory "C-8 version"

Please note that I had migrated from the C-7 to the C-8 once the C-8 came out.

I've had a few issues with this new hub since I purchased it. However, this is the first time I've seen an alert when I logged into the hub. Here what the alert says,

Hub is running low on memory
Reboot as soon as possible.

In the past few months, I've experienced a few times where the hub locks up constantly and will require a full power cycle to fix. I believe those few times are related to this.

Platform version:
Hardware version: Rev C-8

To be clear, I never experienced any issues on my C-7.

Please advise.

You can identify what driver, integration or app is using most of your resources by selecting Logs on the left menu. I would first look at Past Logs tabs for hyperactive devices and apps (you can spot those if you have errors, warnings and events coming in every few milliseconds). Next stop would be Apps and Devices Stats tab.
