Subject [jira] Commented: (LOG4NET-198) Memory leak on a very basic code
Date Fri, 06 Feb 2009 23:59:00 GMT

    [ https://issues.apache.org/jira/browse/LOG4NET-198?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12671377#action_12671377

rauzy commented on LOG4NET-198:
-------------------------------

You can see as well that if you switch the root logging from DEBUG to INFO, you don't have
a memory leak any more so it should be a dispose method somewhere.
