[logback-user] how to disable logback from logging system properties?

Hello Bryan,

At present time, DBAppender merges properties "defined in the 
context***" as well as those properties defined in the current MDC into 
a single map and then persists that map on the database. There is no 
configuration setting to change that behavior.

***Any property defined during configuration is "defined in the context" 
and lives as long as the applications or is changed.

I think that it would be possible to solve the issue you are facing by 
separating properties which should live during logback configuration 
(and then cease to exists) and properties which should live as long as 
the application.

In any case, the problem you describe needs to be fixed. Could you 
please enter a bug report?

Thank you,
