There is already an open DataReader associated

hi all, I've build a website using this linq Architecture. During development everything seems fine. Lately i've run some stress/load testing on the website and i started getting "There is already an open DataReader associated with this Command which must be closed first." If someone knows what this error means or how to prevent it without adding the patch , ill be glad to hear! Thank you!

I think more details are needed. Perhaps you can show us some code? It looks like the reader isn't closed (and the connection is still in use) before executing another command.
