If you look at the description of the error, it says there are 'too many client tasks' - how many SQL references do you have open at a time? Are you trying to write to the database from multiple places by opening and closing the reference each time?

The error message tells you all you need to know.

You have too many ADO tasks runing at the same time.

 From what I can see, you are opening a lot for connections to the same database at the same time. And you are opening and closing them for every loop iteration.

 

Try to change you design to a producer/consumer, where the consumer is the only one that has access to and store data in the database.
