------------------------------------
Summary: Documentation for configuration max-disk-usage is
inaccurate.
Key: ARTEMIS-2246
URL: https://issues.apache.org/jira/browse/ARTEMIS-2246
Project: ActiveMQ Artemis
Issue Type: Bug
Affects Versions: 2.6.4
Reporter: Leo Provido
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.
