First, thank you for answering.
After some log file filtering, I've found out that this issue only
occurs with the HP iLO remote console hosts.
We also have many DRAC (Dell remote access) configured in the same way,
and working fine.
I don't see what role the client plays about the creation of the DHCid -
I thought this was server-driven ONLY... ???
Anyway, the suggestion of Chris still needs to be explored - my next task.
