Arrays Dash board showing blanks

[timwunna]

Pure Unplugged was installed and all the FA and FB were added successfully. It is collecting Data fine. But after running for awhile, the array dash board will show empty and all the analytics dash are not showing blank data as well. When we get to that stage,
1, Unable to add the new FA or existing FA from Pure-Unplugged website.
2. Run the "df -h" command and file systems were not 100% full. May be docker container file system was full. Don't know as I am not too familiar with docker container.
3. Reboot sees to fix the issue. After reboot all the FA and FB are listed again in Arrays dashboard.
4. All the historical analytic data were gone after reboot.
