If this is the case there shouldn't exists a "more than onde lease match the key" on a OMAPI request...right? or i m thinking wrong?If is the last one that counts..
Can anyone test this situation in a recent version?
I m not able the reproduce it in home, probably because there is not enough traffic..and can't upgrade the 3.1.3...

This keeps the client from filling the lease database disk quickly on
