--------------------------------
Summary: [Broker-J] Links for shared durable subscribers are
accumulated in the link registry
Key: QPID-7993
URL: https://issues.apache.org/jira/browse/QPID-7993
Project: Qpid
Issue Type: Bug
Components: Java Broker
Affects Versions: qpid-java-broker-7.0.0
Reporter: Alex Rudyy
Only link with name equals to subscription name is deleted from the link
registry on unsubscribe of shared durable subscription. The other shared
durable subscription links with names containing index are left in link
registry forever. As result, such links can accumulate with time and cause OOM.
The steps to reproduce
* Apply patch from QPID-799
* Start the Broker
* Create shared durable subscriptions with 2 subscribers
* Close subscribers and unsubscribe the subscription
* Dump the link registry state using management operation
{{QueueManagingVirtualHost#dumpLinkRegistry}} . The link for the second shared
subscriber will be present in the dumped data
