starting apache22 in a jail - name-based shared memory failure

[Julian H. Stacey]

Hi all,
Any ideas ?
I have a jail running 9.1-RELEASE in a jail, with a kernel as
shown by uname -a

	FreeBSD land.berklix.org 9.1-RELEASE-p4 FreeBSD 9.1-RELEASE-p4
	#0: Mon Jun 17 11:42:37 UTC 2013
	root at amd64-builder.daemonology.net:/usr/obj/usr/src/sys/GENERIC
	amd64

cd /usr/ports/www/apache22 ; su ; make install ;
cd /usr/local/etc/rc.d # using default httpd.conf
./apache22 stop ; ./apache22 start
tail -F /var/log/httpd-error.log

For comparison, a non jailed 9.1 + apache22 + custom httpd.conf on
another server runs OK with

Is jail disrupting shared memory ?  Or some other problem ? Solution[s] ?
sysctl -a | grep memory
	hw.cbb.start_memory: 2281701376
	p1003_1b.memory_protection: 0
	p1003_1b.shared_memory_objects: 200112
	kstat.zfs.misc.arcstats.memory_throttle_count: 0

Any ideas welcome, Thanks

Cheers,
Julian
