DDF Thread reuse

DDF Thread reuse
We've been seeing some instances where DDF threads are being reused with no change in the user id coming across. This causes headaches for us as we have created WLM classifications based on the thread user id. If a thread gets created with a user id that places it into the High Velocity service class, that is fine. Later on, another request comes in that is assigned to that thread which generates a long running heavy CPU workload. This is where the problem comes in. Based on the type of request, it should have been in the Low Velocity service class.

Is there any way we can get WLM to reclassify the DB2 DDF threads without shutting down thread reuse?
