Hi all,

I installing a new openvz on debian etch via this document [1].
I create a new virtual machine this [1] configrations.
Ok, my vps running normally because i'm try to installing VHCS CP. I have got any error when installation time but i can see not running bind dns server. I try to starting manually (/etc/init.d/bind9 start) but i get

Starting domain name service...: bind/etc/init.d/bind9: line 24: /bin/mkdir: Cannot allocate memory
/etc/init.d/bind9: line 25: /bin/chmod: Cannot allocate memory
/etc/init.d/bind9: line 26: /dev/null: Too many open files in system
/etc/init.d/bind9: fork: Cannot allocate memory

errors. /bin/mkdir is running normally. (mkdir /root/test, ok)

Same problem for proftpd,

/etc/init.d/proftpd: line 13: /bin/grep: Cannot allocate memory
/etc/init.d/proftpd: fork: Cannot allocate memory
Starting ftp server: proftpd/etc/init.d/proftpd: line 94: /sbin/start-stop-daemon: Cannot allocate memory
failed!

Why i get this erros.

Thanks all.

the basic conf is an extremely conservative VPS with 24MB RAM and everything tuned down

use the vzsplit utility to output an 8 way split of your hardware. compare the output of vzsplit with the conf of your VPS and you will see the problem. experiment with vzsplit until you find what you need

that was the solution and as Valmont says the way to check what is happening inside the VPS:

cat /proc/user_beancounters
