High Load in docker on Synology

Is there anything I can do with respect to this. Doesn't do any harm if I see it correctly - but creates some warning messages.

Pi-hole is reporting the system load that it obtains from the OS. If this is not causing you problems, ignore it. If you prefer not to see the warnings, you can disable the load check with a configuration parameter in file /etc/pihole/pihole-FTL.conf:
