[jira] [Commented] (LOG4NET-558) log4net 2.0.7 and greater doesn't log %message pattern

    [ https://issues.apache.org/jira/browse/LOG4NET-558?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15951990#comment-15951990 ]

Chris Bodolus commented on LOG4NET-558:
---------------------------------------

Hmm, in 2.0.8, I tried {code}property{nonExistantKey}{code} in a layout pattern matching yours and it printed _(null)_ in the logs.  It then continued processing the rest of the layout pattern fine.  This was a singled-threaded process.  It looks like you have at least two loggers writing to the same file - could you provide additional insight as to the setup or any additional details that might help to reproduce?
