Have jails been turned on for RPI2?

[bob prohaska]

In the last week or two attempts to run stress2 started
generating console messages of the form

Sep 20 18:24:22 www kernel: pid 870 (swap), uid 1001, was killed: exceeded maximum CPU limit

There's nothing in /etc/rc.conf or /etc/defaults/rc.conf to suggest that jails are enabled.
Should I be looking elsewhere?

Thanks for reading, and any guidance.
