ReadyNas Ultra 6 plus hangs after ~1 week (disks sleeping)

So I'd been encountering a problem where my NAS simply hangs with the LCD blank and non-responsive to a short press on the power button.   Following another post here, I recently upgraded the memory to 4G and was hoping that would solve the problem.   Unfortunately, a week later I encountered the same thing.   This time though I did see the message on the LCD: Disks Sleeping.   The machine was not responding to pings or the admin URL.   Upon rebooting, I see nothing interesting in the logs.   All the disks report being happy.

 

Firmware: 6.10.3

No apps installed

 

Last log message before the reboot:

Snapshot: Snapshot c_1596265229 was successfully created for share or LUN photos.

 

Any thoughts on how to troubleshoot?

 

Thanks

      3.74TB free out of 13.72.    Just a little less than 30% free.

        That's the data volume fullness.  The OS partition is something else - a 4 GB partition that holds linux and the NAS configuration.

         

        You can check it by downloading the log zip file, and then open up volume.log.  Scroll down to the df -h section:

        === df -h ===
        Filesystem      Size  Used Avail Use% Mounted on
        udev             10M  4.0K   10M   1% /dev
        /dev/md0        4.0G  701M  3.0G  19% /
        tmpfs           1.9G     0  1.9G   0% /dev/shm
        ...

        /dev/md0 is the OS partition.
