the situation you described indicates you have two HTWorkitem handlers active which both tries to notify the engine that task was completed. So what I could suggest is:
* double check the code you have where you create HTWorkItemHandler and make sure you have just one for given session
* if you dispose session make sure that your handler is disconnected otherwise you'll get exceptions as handler will try to notify disposed session

Hi, Maciej!
     I do appreciate your timely help! I finally find out there are multiple ksessions in my code. Now no words can describe how excited I am. How careless I was!
     Thank you again for your generous help.
Best Regrads!
