Yes I've had the same problem. One system runs just fine with it's jails, and another crashes habitually. It has to do with a certain jail (and services). Our system are set up to be able to move jails between them (great for backups and near perfect uptime), and a certain set of jails always hangs the system in this way. I'm trying to narrow it down. Do you get a core dump or does it just hang?
