Hello,

I want to ask you some questions:

1. Kernel you're using


2.6.18-ovz028stab031.1-smp

Quote:

2. You write "disk IO goes very high". Can you be more precise? Please, post tools output and other appropriate stuff.


This was only my interpretation.

Quote:

3. You write "...the system is no more usable". What do you mean? The response of the system is very long? Can you give some certain examples?


Last night I made a vzdump of about 10GB in 6 VEs. Average system load (see it with command w or with top) went to over 50.0 for about 2 hours. I hid Ctrl-C and it took about half an hour to stop vzdump.

Quote:

4. You write "average load more than 20!". Sorry for my ignorance, where do you get this digit (20) and what it means? Wink


output of top or w
I see it in a gkrellm client too.

At the same time, cpu usage is about 0% - 1%
