This usually happens when there are no processes running in the jail to keep it up. By default, jails started thru rc.d/jail are not persistent. Try adding something like cron_enable=YES to rc.conf inside the jail. The /etc/rc.d/jail script will (by default) run /bin/sh /etc/rc as the jailed process. On FreeBSD, /etc/rc is responsible for booting the system. By default, a vanilla FreeBSD jail will run syslogd, sendmail, and cron, all of which fork and daemonize, triply allowing the jail to persist. CentOS -- which also has /etc/rc (as a symbolic link to /etc/rc.d/rc) -- meanwhile may not have any services that are enabled by default. I would either a. chroot(8) into the jail and use chkconfig(8) to enable something like cron in runlevel 5 (e.g. chkconfig --level 5 crond on) or simply... b. ln -sf ../init.d/crond /tank/jails/centos/etc/rc5.d/S90crond On a side note: this is the first that I've ever heard that you could run CentOS Linux in a FreeBSD jail. It should work -- afterall, my CentOS 4.7 box appears to have /etc/rc as a symlink to /etc/rc.d/rc, so in-theory there should be no problems with the /etc/rc.d/jail FreeBSD script from firing up a CentOS jail (*cough* in-theory *cough*).
