If you know what information you want to keep and what you want to discard, then you should be able use MDC.getCopyOfContextMap() and MDC.setContextMapValues() to clean up the MDC. But you'll need to figure out when to call them based on the API that the thread-pool exposes to you.

Hello, I am using logback version 1.1.3. I have a situation where the MDC is getting copied over to thread pools that I don't manage and filling my logs with log statements that contain MDC information that is no longer valid. Because I don't manage these thread pools, I am not able to copy the correct values to that thread pool when threads get used/re-used). Does anyone have a solution for this problem? -Joshua ------------------------------------------------------------------------------ CONFIDENTIALITY NOTICE: If you have received this email in error, please immediately notify the sender by e-mail at the address shown.
