Subject [jira] Reopened: (ODE-576) ProcessDaoImpl objects get leaked when using in-memory-processes
Date Thu, 09 Apr 2009 21:43:13 GMT

Ciaran Jessup reopened ODE-576:
-------------------------------


Based on my comments above, the BpelConnectionDaoImpl instance that the 'delete' occurs on,
is different to that which the 'create' occurs on, so the 'remove' that happens to the internal
'store' is happening on the JPA instance not the memdao instance, personally I've not got
a clue what this means, but there *is* a leak there, sadly with the easter close down I can't
get a screen shot to show you the before + after reference graphs w GC root routes highlighted,
but its a very easy to find memory leak, just do multiple deply + un-deploy cycles of in-memory
processes, you will see the _Store references in the BpelConnectionFactoryImpl object increase
by one for each deployment, and never decrease.....

> It seems that when I deploy and un-deploy in-memory processes ProcessDaoImpl objects
stored in the __StateStore field of the BpelDAOConnectionFactoryImpl object are being left
around.
> Over the course of several tens/hundreds of deployments the memory contained in these
objects mounts up substantially :(
