First I can confirm this bug. Some time ago I had two servers which caused a huge amount of dhcp requests to log the DHCP server (managed by a different departement). They told me one server did 30 requests per seconds.
I've looked at the CentOS 8 sources and found this patch: > # If we receive a DHCP offer in dhclient and it's DECLINEd in > dhclient-script, > # backoff for an amount of time before trying again > %patch6 -p1 -b .backoff The patch is in the directory SOURCES called dhcp-dhclient-decline-backoff.patch. Since I'm not good in C programming it would be good I someone else can have a look if Debian should include this patch. I'll attach the patch from Centos.
dhcp-dhclient-decline-backoff.patch
