Abandoning ip address issue

[Suresh Rajagopalan]

Thanks for the responses.   This was caused due to a omapi client (foreman
in this case) which was wrongly configured to allocate addresses from the
pool.  Foreman allocates as fixed addresses and so obviously this
configuration caused the problem.
