>             Project: ActiveMQ
>          Issue Type: Bug
>          Components: Broker
>    Affects Versions: 5.9.0
>            Reporter: Gary Tully

>             Fix For: 5.10.0
>
>
> missing reference count on filepending message cursor allows unlimited messages to be loaded into the broker.
> The periodic messageExpiry task does a forced page in, that does not seem to respect a memory limit, even if it is correctly calculated.
> disabling message expiry avoids the issue.
