Follow-up Comment #4, bug #27049 (project lwip):

No, the IDs are unique.

Looks like a timing issue.  The DHCP server seems to take longer to handle
multiple requests and so lwIP starts asking for repeated "Requests".  It
doesn't complete in my 10 second timeout before I fall back to a static IP. 
I'm going to see if 20 seconds helps.  It appears if lwIP were a little more
patient, it would get the response before it re-requests again and it would
all complete faster.  Attached is a pcap of 4 devices coming up together which
takes more than 10 seconds to complete. 

(file #18430)
