>
> Key: AMQ-3070
> URL: https://issues.apache.org/jira/browse/AMQ-3070
> Project: ActiveMQ
> Issue Type: Bug
> Components: Broker
> Affects Versions: 5.4.2
> Reporter: Adam Sussman
> Priority: Critical
> Fix For: 5.6.0
>
>
> Discovered while authoring a custom SubscriptionRecoveryPolicy.
> When function 'recover' is being run, no new connections to the broker can be made. All connection attempts hang until 'recover' returns.
> This is a huge problem when recovery takes any amount of time. In my particular case, recovery can take many minutes.
> Note that this problem also prevents the addition/removal of consumers and producers in general, so any threads needing to do so are also blocked.
> The issue appears to be a lock on RegionBroker.purgeInactiveDestinationsTask. I would attempt to fix, but I am unsure of the consequences of messing with this lock and I am unclear on what is being protected here.
