My Pi 2B has been running for months and every once in a while I get this report "Anomaly report for PiAware feeder with a MAC address of b8:27:eb:18:4a:83:
This feeder is not being used for multilateration because its timing information appears to be unreliable. This can be caused by the site location being incorrect, or because your Pi is running out of free CPU.
How do I remedy this? I think last time I just rebooted.
