I got apache22 repeatably failing & working, by including & excluding
	ScoreBoardFile /var/run/httpd.scoreboard
so as I didnt need ScoreBoardFile anyway, I've commented it out.

	http://httpd.apache.org/docs/2.2/fr/mod/mpm_common.html#scoreboardfile
further up in page talks of chroot, but not exactly in that section.

Thanks also to <cafedjian.g at ovh.fr> for off list sugestion 
	Check witch sysctl that security.jail.sysvipc_allowed = 1.
All my httpd hosts (jailed & not) run OK showing 0 for
	sysctl security.jail.sysvipc_allowed
Just the jail host refuses sysctl security.jail.sysvipc_allowed=1
But that's no problem, just another sign of in jail. 
Thanks Mateusz & cafedjian.g

Cheers,
Julian
