>          Components: karaf-core
>    Affects Versions: 2.4.3
>            Reporter: Gert Vanthienen

>             Fix For: 2.4.4

>
> When using the file locking mechanism, the passive/slave node will keep on opening ports with the shutdown hook. 
> Adding a guard to prevent the locking loop from setting up multipe shutdown ports/threads should be enough to fix the issue on 2.4.x
> The problem doesn't occur on 3.0.x or above, because of the changes in the locking mechanism implementation.
