A few things. Can you provide more information about what did not work when you set the zone's memory cap? Right now you've given us nothing to go on. If you have questions about how the zone memory cap is expected to work, I'll try to answer them. Second, although the design center for smartos does not include the kind of customization you've done in the global zone, I would be interested in debugging the live lock you're in. If you're willing to provide a panic dump, I'd like to take a look at it.
