VC has a point, it might involve a circular reference, the phrase "a call to create a database object (which creates the db connection) and assigns it to $self->{dbo}" surely sound circular-referency. Could you try using delete instead of undef? Maybe it helps.

However, deep in my heart, I don't really believe it, this has the fault smell of a bug in Perl.

For debugging purposes, to see if any attempt is being made to clean up the object, you can add print statements in a DESTROY handler — use Hook::LexWrap or another similar module if one already exists and you don't want to edit the source; or subclass the class of the database connection.
