I got this one today, from a robot which is running on a permanent basis. This is very rare. I got that one before. But, the number of loop processes this robot could do before I have such a situation could be in the hundreds of thousands.

"There is already an open DataReader associated with this Command which must be closed first."

I am trying to understand the situation so I can resolve it. Anyone had experience that one before and would be able to provide some info?
