Subject [jira] Commented: (ODE-576) ProcessDaoImpl objects get leaked when using in-memory-processes
Date Thu, 16 Apr 2009 08:19:14 GMT

    [ https://issues.apache.org/jira/browse/ODE-576?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12699579#action_12699579

Ciaran Jessup commented on ODE-576:

Hi Karthick,
Unfortunately your patch doesn't seem to actually do anything :) 

The reason it doesn't do anything is because the new BpelEngineImpl.isInMemory call relies
on the passed process Id being stored in the _activeProcesses list in order to determine whether
or not the process is in memory or not.

Unfortunately when an UNDEPLOYED event occurs and is caught in ODEServer.handleEvent code,
this code executes:

The 'unregister' code *removes* the process from the _activeProcesses list that is later checked
transitively from within the cleanupProcess, because it is never there, the process is never
found, so it can never be checked as being 'in-memory'.

Hope this helps :)
