Hello Lucas, Thank you for reporting this issue. I have created a jira entry for it: http://jira.qos.ch/browse/LBCLASSIC-104 The issue has been solved in revision 2128. Best regards, Lucas, Casey wrote:
I'm seeing unexpected behavior when I combine MDC and SMTPAppender. The MDC values appear to be lost for previous log messages when MDC.clear is called before Logger.error triggers the actual email. This does not appear to be a problem with console appender. Below is a test program that will reproduce the problem. A logback.xml that uses an SMTPAppender and a pattern that includes %mdc is required.
Is there something I'm missing?
