The problem is still present in 7.0-RC1:
FreeBSD cassini.grimmbrothers.com.ua 7.0-RC1 FreeBSD 7.0-RC1 #0: Mon Jan 28 
16:57:47 EET 2008     root_at_cassini:/usr/obj/usr/src/sys/GENERIC  amd64

After executing "/etc/rc.d/jail restart php_cgi"
I see a jail without a processes:

root_at_cassini:/home/www/# jls                                                                                                                                                             
   JID  IP Address      Hostname                      Path
     2  xxx.53.51.236   php-cgi  /home/jails/php-cgi
     1  xxx.53.51.236   php-cgi  /home/jails/php-cgi
root_at_cassini:/home/www/# ps awwx -o jid | grep 1 | wc -l                                                                                                                                 
       0
root_at_cassini:/home/www/# ps awwx -o jid | grep 2 | wc -l                                                                                                                                 
      13 

Also i am using nullfs to mount some directories for this jail, however i 
am not sure if it's related to the problem.
