Do you use ZFS? We have an internal software (some sort of monitoring agent) that also hangs in jails, from time to time. The guy who wrote it found out it’s because of mmap (I don’t know the specifics). The processes end up as unkillable in „D“ state and we need to reboot the hosts to fix it. As the purpose of the hosts is not to run the agent, we usually let it hang and restart when it’s convenient. The systems are FreeBSD 10.3, though (running nginx and varnish in different jails).
