Hi, Servers never guarantees that thread allocated to a request from client would be given the same thread on subsequent requests from the client. Hence its advisable to clear out the mdc info before the request ends(preferable)or in case you wouldn't like to clean up then make sure you overwrite it every time to get the correct output.
Hope this helps!!

The application server is IBM WebSphere 6.1 and it uses thread pools. So, sometimes, the thread for some sessions is changed (the pool allocate another thread to continue the session) and since the MDC is thread based, in this cases I'm getting a incorrect session on the log records. The log's are scrambled now. Any suggestions?
