Hi all,
I have two servers (svr02 and svr07) with OpenVZ systems and both have cpanel / WHM installed outside containers.
1. Dual Xeon Quad-core (8 Processors) with 12gb RAM:
Linux svr02 2.6.18-92.1.1.el5.028stab057.2ent #1 SMP Mon Jul 21 21:48:02 MSD 2008 i686 i686 i386 GNU/Linux

2. Quad Xeon Quad-core (16 Processors) with 12gb RAM:
Linux svr07 2.6.9-023stab048.4-enterprise #1 SMP Fri Jul 11 20:18:05 MSD 2008 i686 i686 i386 GNU/Linux

When the crontab runs the script cpbackup (to create backups of accounts outside VPS) my server svr07 get high load average in 12.0 10.0 9.0 and all containers are without work without access ssh, web, email etc..

Someone went through this problem? How I do to solve this?

Thanks in advance.

Hi, thanks for this reply.
The cpbackup script (of cPanel) create backup's from user accounts in /home /home2 /home3 ...

I have various accounts in HN and I need to create backups daily. But I have four VN in this same server.

Additional informations about this server:
[root@svr07 ~]# /usr/sbin/vzcpucheck -v
VEID CPUUNITS

0 1000
101 1000
103 1000

Current CPU utilization: 4000
Power of the node: 1711890

[root@svr07 ~]# /usr/sbin/vzmemcheck -A

[root@svr07 ~]# uname -a
Linux svr07 2.6.9-023stab048.4-enterprise #1 SMP Fri Jul 11 20:18:05 MSD 2008 i686 i686 i386 GNU/Linux

When the cpbackup run at 1 hour AM, all my VN they stay incommunicable. My NMS (nagios) it stays crazy, sending e-mails that everything is offline as if I stop all the VNs

and when this script finishes, all VNs return to be working normally.

I have installed openvz in two servers and this problem it only occurs in one of them.

You knows what I can make to solve this problem?

Sorry for my bad english.
