It's not neccessarily strange - but we can't tell without logs.

We can't tell what the problem is without seeing
the logs that go with these leases, but my best
guess would be :
1) Client is not getting a response back from the
server in response to dhcp-request. It is
resending the request every 2s which results in
teh server creating a lease lease file entry each
2) Client is getting response but not accepting it for some reason.
First step is to look in your logs and tie-up
stuff in the logs with what's in the lease file -
that should give a bit more information about
what is going on.
