Alex Rudyy updated QPID-8156:
-----------------------------
Description:
{{SystemNodeRegistry}} of deleted {{VirtualHost}} is still referenced after
virtual host node deletion. It prevents VHN/VH garbage collection. The
reference to registry is hold by
{{TrustStoreMessageSourceCreator$TrustStoreChangeListener}} which is registered
on broker as part of invocation {{TrustStoreMessageSourceCreator#register}}.
The user impact is minimalistic as it is not expected that virtual host nodes
are often created and deleted in production environment.
Broker restart should resolve the issue.
Steps to reproduce:
# create BDB HA virtual host node
# delete BDB HA virtual host node
# collect heap dump and check references to deleted virtual host node
{noformat}
select * from
org.apache.qpid.server.virtualhostnode.berkeleydb.BDBHAVirtualHostNodeImplWithAccessChecking
{noformat}
