Subject [jira] Commented: (OPENJPA-441) Memory increase when deleting objects
Date Thu, 15 Nov 2007 10:29:43 GMT

    [ https://issues.apache.org/jira/browse/OPENJPA-441?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12542732

Christiaan commented on OPENJPA-441:
------------------------------------

I've no statistics on this yet. As mentioned in OPENJPA-439 there was an increase in each
transaction in memory usage and I believe this extra part was not cleared after commit, but
with the supplied patch that should be fixed. I also noticed that after commit the memory
usage roughly drops back to the level when the transaction started (included in the attached
screenshots in 439), so I don' think there is a memory problem accros the commit boundary.
