>             Project: ActiveMQ Artemis
>          Issue Type: Bug
>    Affects Versions: 2.6.4
>            Reporter: Leo Provido
>            Assignee: Justin Bertram
>            Priority: Major
>             Fix For: 2.7.0

>          Time Spent: 2h 50m

> During the execution of tests involving sending messages to the System, we observed that the System started blocking messages before the disk is full.
> According to the Configuration Reference ([https://activemq.apache.org/artemis/docs/1.4.0/configuration-index.html]) documentation, the default value of the configuration max-disk-usage is 100. However, we discovered that the actual default value of max-disk-usage is 90. The file inspected is ./etc/broker.xml. Thus, the documentation is deemed inaccurate.
> We have the opinion that severity of this incident is Major because a) the documentation provides an inaccurate piece of information that influences the way we design our mitigation strategies for risks surrounding hardware resources utilization, and b) we don’t necessarily have the bandwidth to review all default configuration values.
> Inaccurate information may cause failure to provide message brokering services despite mitigation strategies being in place.
