   @sleungtoast Thanks for reporting. We also discovered this issue and had already a plan for fixing it. @jerrypeng is working on that. 
   
   The fix is two-fold: 
    * Double check the pending messages and return error to producer when the dup status is uncertain (eg. message is still pending)
    * Sync back the lastPushed map with the lastStored map after the failures
