Almost none of this sounds right. If you're only running with a zone memory cap then you certainly never want to use the rcap daemon, since that only is for projects on smartos. That svc is disabled by default, so I assume you enabled it? What does your zonecfg look like? Why aren't you using the normal zone memory capping mechanisms? What crashed? Is there a panic or dump we could take a look at? What platform are you running?
