Do I understand it right, that you made it a reproduceable testcase? If so, can we have a look on it?

Thanks Chuck. I have done some further research and I have the impression that there is some kind of race condition where a session that is being removed because of a timeout is also handling requests. The loggings indicate that a session is destroyed but then nevertheless a doGet is invoked with a request parameter that refers to that timed out session. If I crank up the timeout, seriously reducing the chances a session times out before it has completed all the client requests it is supposed to handle during the test, the problem does no longer occur. I am not sure where that leaves me. I am still uncertain as to what the servlet is doing wrong. Would you (or anyone else) have any other comments on this?
