I have an intermittent issue with static leases. Sometimes when I add a lease it breaks the Nslookup. Rebooting does not fix it. If I delete the entry and save, it works again. If I then add the same entry again it most often works properly. I get the impression that the problem must be some sort of corruption of the file containing the static lease information, which can be repaired by deleting the last added entry. Has anyone else experienced this ?
I now realise that the problem is duplicate entries.
If I remove the duplicate entry all is fine.
log attached.
