Is there an issue with vzsplit - if i use any value less than 15 i get the same value for PRiVVMPAGES and VMGUARPAGES (and others but these are ones that concern)

[root@vps ~]# vzsplit -n 1 | grep -E "VMGUAR|PRIVVM"
VMGUARPAGES="504818:2147483647"
PRIVVMPAGES="504818:555299"
[root@vps ~]# vzsplit -n 10 | grep -E "VMGUAR|PRIVVM"
VMGUARPAGES="504818:2147483647"
PRIVVMPAGES="504818:555299"
[root@vps ~]# vzsplit -n 12 | grep -E "VMGUAR|PRIVVM"
VMGUARPAGES="504818:2147483647"
PRIVVMPAGES="504818:555299"
[root@vps ~]# vzsplit -n 14 | grep -E "VMGUAR|PRIVVM"
VMGUARPAGES="504818:2147483647"
PRIVVMPAGES="504818:555299"
[root@vps ~]# vzsplit -n 15 | grep -E "VMGUAR|PRIVVM"
VMGUARPAGES="83261:2147483647"
PRIVVMPAGES="499566:549522"

The head of vzsplit shows the following:

# Configuration file generated by vzsplit for 10 VEs
# on HN with total amount of physical mem 3286 Mb
# low memory 854 Mb, swap size 1983 Mb, Max treads 8000
# Resourse commit level 0:
# Free resource distribution. Any parameters may be increased
# Primary parameters


As i was only doing a split of 10 this was totally over allocating resources.

This is happening using Fedora5 and Fedora6 as the main HN.

Also two seperate kernels

Linux xxxx 2.6.18-ovz028stab027.1-smp #1 SMP Mon Apr 9 16:21:10 MSD 2007 i686 i686 i386 GNU/Linux

and

Linux xxxx.com 2.6.18-8.1.15.el5.028stab049.1 #1 SMP Thu Nov 8 16:23:12 MSK 2007 i686 i686 i386 GNU/Linux

Any ideas on the cause of this and how to fix? This has caused an issue as without realising it was seriously over commiting resources, deliberatly used the vzsplit command to avoid this happening!
