Ok but this doesn't change I always have ulimit -n 1024 but the
ulimits/nofile is 524288

Curiously when connect the guest with command "vserver guest enter" the
ulimit -n give 524288 but if I connect by SSH on guest the ulimit -n
give 1024 and I can't set the ulimit by command "ulimit -n 524288" that
give me operation denied !?

I use 2.6.26-2-vserver-686-bigmem on Debian squeeze/sid
