I know what secs is for, thanks.

That's not the issue here.

The issue is that a server is receiving two copies of the DISCOVER a few 
milliseconds apart with different giaddr, but only responding to one.

The "min-secs" setting could, in theory, cause it to ignore *both*. But:

  a. We have no min-secs on the affected server, and
  b. secs==0 in the affected packets
