The support team is awesome!
However, I think the issues -we- are experiencing have more to do with the network than the product. I have been experimenting with network card settings, switch settings and verifying my suspicions through Wireshark. Hopefully, I will be able to write up my findings in a blog. So far, the tweaks I have made have helped.
Just wanted to confirm for the original user that yes - hangs have been seen. Frequent? no. Cause? unknown as of yet to me. Once I can eliminate the state of the network as being a potential cause, then I can turn my attention back to any issues with the product.
This product rocks - I love it :)
