I have created a new centos-5-x86_64-minimal VPS.

When i try enter, i get error

[root@server12 ~]# vzctl enter 233
entered into CT 233
-bash: /etc/profile: Cannot allocate memory
-bash: /root/.bash_profile: Cannot allocate memory
-bash-3.1#
-bash-3.1# free -m
-bash: start_pipeline: pgrp pipe: Cannot allocate memory
-bash: free: command not found
-bash-3.1#



I have another Ubuntu VPS on this server, that work properly. I stop Ubuntu VPS and start this new CentOS VPS as both use same IP. Only CentOS VPS give this Memory error.

VPS configuration for CentOS VPS is

[root@server12 ~]# cat /etc/vz/conf/233.conf

This is a bug or CentOS (centos-5-x86_64-minimal) need memory run than Ubuntu VPS (ubuntu-10.04-x86_64) ?



Anyone know how to fix this ?

Hi,

Reboot your VPS once and try to enter into the VPS.

Thanks.

I tried that, still not working.

I created a CentOS 32 bit and Fedora 14 32 bit, both worked fine with out any memory error. On CentOS 32 bit VPS, i am able to install XFCE, Opera and VNC server, so i don't think it is a memory issue.
