Subject [jira] Created: (AMQ-2530) memory leak in ConduitBridge (subscriptionMapByRemoteId)
Date Sun, 13 Dec 2009 11:01:52 GMT
memory leak in ConduitBridge (subscriptionMapByRemoteId)

                 Key: AMQ-2530
             Project: ActiveMQ
          Issue Type: Bug
    Affects Versions: 5.3.0
            Reporter: Mario Lukica

I believe there is a memory leak in ConduitBridge - looks like DemandSubscriptions are not
removed from subscriptionMapByRemoteId when remote RemoveInfo is received.

removeDemandSubscription normally removes subscription from subscriptionMapByRemoteId in DemanForwardingBridgeSupport,
but method is overriden in ConduitBridge and only removes subscription from subscriptionMapByLocalId.

Leak becomes more significant when consumers are connecting very often (i.e. few connections
per second), and bridge connection is stable (lasts for couple of days without reconnecting).
MessageConsumer's are not pooled and subscriptions are created and removed often (and forwarded
via bridge).
