what's wrong?

2nd question: I have two virtual servers. The first starts with:
chbind --ip 192.168.213.103 -- \
vcontext --create -- \
vsched --fill-rate 95 --interval 100 --tokens-max 200 --tokens 100 -- \
vuname --xid self --set -t nodename=peet.spb.ru -- \
vattribute --flag sched_prio -- \
sctxinfo /var/run/rt-network/virtual/peet.spb.ru -- \
`which env` -i PATH=$PATH `which vcontext` --migrate-self --endsetup -- \
reducecap --secure -- \
chroot . /usr/local/sbin/init -i /dev/initctl -t /etc/inittab
and I've got then:
~ # cat /proc/virtual/49156/status
UseCnt: 239
Tasks: 66
Flags: 0000000300000200
BCaps: 00000000344c04ff
^^^^^^^^^^^^^^^^^^^

sctxinfo is an sh scripts that saves current xid to the file and exec() string after "--"
The second starts:
chbind --ip 192.168.213.102 -- \
vcontext --create -- \
vsched --fill-rate 95 --interval 100 --tokens-max 200 --tokens 100 -- \
vuname --xid self --set -t nodename=apache2.hst.ru -- \
vattribute --flag sched_prio -- \
sctxinfo /var/run/rt-network/virtual/apache2.hst.ru -- \
`which env` -i PATH=$PATH `which vcontext` --migrate-self --endsetup -- \
reducecap --secure -- \
chroot . /usr/local/sbin/init -i /dev/initctl -t /etc/inittab
~ # cat /proc/virtual/49160/status
UseCnt: 24
Tasks: 9
Flags: 0000000300000200
BCaps: fffffffffffffeff
^^^^^^^^^^^^^^^^^^^
CCaps: 0000000000000000

Why I got normal security in the first case and no security at all in the second?
Thanks.
