Well, I disagree with your "it's not a problem" statement because OP said, "This caused us to hit our softcap and affected other tasks in the system." The softcap issue could be resolved by Dave Thorn's suggestion of putting it into a resource group with a max specification. Other sites may not necessarily have the bandwidth to support NDM eating half an engine; if the bottleneck is in the pipe then they won't necessarily see ugly CPU consumption. -- Tom Schmidt
