Server down frequently - Multiple ip

Question

I've a dedicated CentOS server and I need multiple IPs, I've installed 3 ips

So: ifcfg-eth0 is:

DEVICE="eth0"
BOOTPROTO="static"
DNS1="127.0.0.1"
GATEWAY="95.141.37.1"
HWADDR="60:A4:4C:4F:90:01"
IPADDR="95.141.37.85"
IPV6INIT="yes"
NETMASK="255.255.255.0"
NM_CONTROLLED="yes"
ONBOOT="yes"
TYPE="Ethernet"
UUID="01535d92-a759-4fff-a80c-3e3637d64907" 

ifcfg-eth0:1 is

DEVICE="eth0:1"
BOOTPROTO="static"
DNS1="127.0.0.1"
GATEWAY="95.141.37.1"
IPADDR="95.141.37.159"
NETMASK="255.255.255.0"
ONBOOT="yes"

ifcfg-eth0:2 is

DEVICE="eth0:2"
BOOTPROTO="static"
DNS1="127.0.0.1"
GATEWAY="95.141.37.1"
IPADDR="95.141.37.198"
NETMASK="255.255.255.0"
ONBOOT="yes"

Where's the error?
