--------------------------------------

             Summary: Log warning if server can crash on OutOfMemory due to "misconfiguration"
                 Key: ARTEMIS-201
                 URL: https://issues.apache.org/jira/browse/ARTEMIS-201
             Project: ActiveMQ Artemis
          Issue Type: New Feature
          Components: Broker
    Affects Versions: 1.0.0
            Reporter: Miroslav Novak


Imagine situation where server is started with 3000 destinations and max-size-bytes is set
to 10MB. This would mean that JVM would have to be started with at least 30GB of memory to
prevent OOM in case that all destinations get filled up. (PAGE mode is not a solution in this
case as it starts once destination exceeds 10MB in memory)

Purpose of this jira is to provide check which would print warning in case that such OOM can
happen. This check would be executed during start of server and then with adding any destination
at runtime.
