Lots of fairly recent posts online regarding panics in day-to-day use. Using them in production seems risky. Is there something I should be looking at in particular? When you say shared-IP jails, what exactly are you referring to? I'm not sure what's shared in this case; I have one public IP (it's a VPS) but individual jails are on their own private loopback addresses. M
