Danushka Menikkumbura commented on QPID-3162:
---------------------------------------------
When I investigate I see a number of references (some are circular) among some
transport-level objects like MINANetworkDriver, Connection,
ProtocolEngine_0_10, etc which prevent the objects from getting GC'ed. Also
there is a synchronisation issue in closed() method in
org.apache.qpid.transport.Connection that occurs when it tries to set
connection state to CLOSED that in turn prevents corresponding
ProtocolEngine_0_10 object from getting removed from the _typeMap in
org.apache.qpid.server.configuration.ConfigStore eventually. Hence a memory
leak per connection.
