Some parts of what's shown in your selected fragment from the lease
unsurprising; others appear really strange. I suspect bizarre client
but can't be sure.
The client presents with 2 "instances": uid respectively present or
Separate treatment of the two is to be expected
The leases given for the instance with uid are "normal" in that they
Distinct IP addresses are surprising unless you have so much churn
and so little
headroom that between 20:02:27 and 20:17:37 (just over 15 minutes),
has already been given the address leased earlier.
The leases given for the instance where the uid is missing show
The first two leases are for consecutive, but contiguous time
periods, yet are for
different addresses. This should only happen if your churn/headroom
is such that in less than 1 second, another client has acquired the
second and third leases overlap by 5 seconds.
More is going on here than is apparent from the lease file.
Can you extract the log entries for the addresses and corresponding
in your lease-file fragment? This may help.
