Subject [jira] [Created] (AMQ-3813) limit the number of producers and consumers created by a Connection
Date Fri, 20 Apr 2012 09:52:40 GMT
limit the number of producers and consumers created by a Connection
-------------------------------------------------------------------

                 Key: AMQ-3813
                 URL: https://issues.apache.org/jira/browse/AMQ-3813
             Project: ActiveMQ
          Issue Type: Improvement
          Components: Broker
    Affects Versions: 5.5.1
            Reporter: Rob Davies
            Assignee: Rob Davies
             Fix For: 5.6.1


Sometimes a rogue client can create an unlimited number of producers or consumers if not developed
correctly. The client is in effect launching a denial of service attack on the broker - as
it will eventually run out of memory, storing ProducerInfos and ConsumerInfos. This enhancement
enables the number of consumers and producers to be limited per connection - by adding maximumProducersAllowedPerConnection
and maximumConsumersAllowedPerConnection properties to the transport connector - e.g.

<amq:transportConnectors>
   <amq:transportConnector uri="tcp://localhost:61631" maximumProducersAllowedPerConnection="5"
 maximumConsumersAllowedPerConnection="10"/>
</amq:transportConnectors>
