99% performance wa, slow server.
There is a big problem with the server (VPS based on OpenVZ, CentOS 5, 3GB RAM). The problem is the following. The first 15-20 minutes after starting the server is operating normally, the load average is less than or about 1.0, but then begins to increase sharply% wa, then hovers around 95-99%. Load increases to 85-99 and even the server via ssh is not able to respond quickly to anything. Tell me how you can discover what could be the problem. Thank you.

dtc_setup_vps_disk
dtc_setup_vps_disks(8) System Manager's Manual dtc_setup_vps_disks(8)
NAME
dtc_setup_disk - setup LVM disks for using it as a VM
SYNOPSIS
dtc_setup_vps_disk.sh VPS_NUMBER HDD_SIZE SWAP_SIZE [ lvm|loopback ]
DESCRIPTION
dtc_setup_vps_disk.sh This shell script is a part of the dtc-xen package that is to be used by the dtc panel to manage a Xen VPS server.
This script is used to create partitions to be used by a VPS later on. It will create a normal partition that will be used as a root disk,
and a swap partition.
dtc_setup_disk is to be used by the dtc-xen SOAP server, but can also be used as a standalone userland tool.
If the partition(s) exists, then this script will delete it/them first.
OPTIONS
VPS_NUMBER has to be a number between 01 and 19. Let's say the number is 16, and that dtc-xen is configured to use the volume group called
lvm1, then this script will create /dev/lvm1/xen16 and /dev/lvm1/xen16swap.
HDD_SIZE Size in MB of the VPS partition to create.
SWAP_SIZE Size in MB of the VPS swap partition to create. If the dtc-xen SOAP server is used to create the VPS, then it will create a swap
partition of the exact same size as the memory.
IMAGE_TYPE This parameter can have 2 values: either lvm or loopback. If ommited, then lvm is used. If lvm is used, then this script will
create a partition using lvmcreate, otherwise it will create an image file. Both will later be used for the VPS.
EXAMPLE
dtc_setup_vps_disk 04 15360 256 lvm
This will create 2 LVM partition to be used by the VPS named xen04, the first one being a root partition of 15 GB, and the second one being
a swap partition of 256 MB.

This documentation describes dtc_setup_vps_disk version 0.3.15. See http://www.gplhost.com/software-dtc-xen.html for updates.
