While studying the performance of WD on the sites to which I have remote access, I have noticed that WD Pi4 site, especially those which only 1 GB or 2 GB of RAM, seem to use swap space which is generally a sign of the system starved of memory, for example:
If 'top' shows such a condition on your Pi (or other memory-constrained PC) and it is configured to bring up a graphical desktop which you aren't using, then it is easy on a Pi to free a lot of memory by changing the Pi to boot up with a terminal mode desktop. To do that from a terminal window on the Pi, run 'sudo raspi-config' and select 'Boot options' .
Some WD installation have run for weeks or months without rebooting, so I'm not aware of any memory leaks within WD. But please let me know if you see any!
