com.pega.pegarules.pub.context.StaleThreadError: Thread has been recycled ?

Hi there,

We have seen in PROD log, what would cause this and would this have impact on the slowness of the production.

Can you trace this to see if it occurs in conjunction with RedirectAndRun being called ?  In particular, noticed the last step of that activity where threads are cleaned up.  Is it cleaning up the thread that is then attempted to be used later, and that attempt is throwing the error ?  /Eric

Hi Eric,

  We cannot anticiapate when this will happen, I guess I cannot set the trace on at all time.  Would stack trace gives us a clue?
