I think this is an Erlang bug, but we need to dig down further to check -
it looks to me like Erlang is interpreting a value as signed, when it's
actually unsigned. Hence Erlang and correspondingly Rabbit thinking you
have negative amounts of memory installed.

We shall investigate further. Many thanks for your help,
