Tao, Seems the issue is not with new query having same handle. But the other values seem to differ - esp. driverEndTime.
Couple of options for you not to see the exception any more : 1. Clear lens server persist state and restart. or 2. Remove the entry from DB corresponding to the problematic query handle. Can you raise a bug with the above exception to get it fixed properly?
