what version are you using? not the latest I guess
Not sure of your question though - what "Reason" are you looking for? I imagine this machine has activated twice, and the previous entry was not removed in between?
We are using 5.2.2 version. and just want to know that how it will create the same entry on the database genrally it don't allow to create it. But i want to know just RCA forthe same.
I think the bug is related to the name cache. I think if you put something in the bin, then restore it, the system will then allow you to create a duplicate because the restore function does not re-add the name into the cache.
it's fixed in the current release.
