Not cloning cgroup for unused subsystem ns

I has a problem many days about kernel message("Not cloning cgroup for unused subsystem ns");
evnironment:
OS: Linux server0 2.6.26-2-amd64 #1 SMP Thu Sep 16 15:56:38 UTC 2010 x86_64 GNU/Linux Debian GNU/Linux 5.0 \n \l
mechine: IBM systemX 3650 M2

I think that is the vsftpd problem,because causing the problem when ftpuser logining.
a ftpuser logining message:
1./var/log/message:

our vsftpd service has vsftpd-2.2.2+pam_mysql-0.7RC1+mysql-5.1.48,it's compiled by myself.

some message when vsftpd restart: /var/log/message
  Aug 21 10:24:44 server0 kernel: [ 6015.791665] warning: `vsftpd' uses 32-bit capabilities (legacy support in use)
