High CPU load on server side

Post by po4talion » Fri Apr 11, 2014 10:41 pm

I've just installed SoftEther VPN Server on Ubuntu 13.10 x86
VPN server constantly takes 95-99% of CPU time.
VPN Client v4.06 Build 9435
VPN Server Ver 4.06, Build 9437, beta

Update: I think the reason of high load is the huge network trafic generated by vpn client when I try to connect. It looks very strange. You can see the moment I connected vpn client(red arrow) on screenshot.

Do you use LocalBridge and SecureNAT? If so, packet is loop.

In your vpn_server.config file, there is Local Bridge setting.

declare LocalBridgeList
{
declare LocalBridge0
{
string DeviceName eth0
string HubName VPN
bool LimitBroadcast false
bool MonitorMode false
bool NoPromiscuousMode false
bool TapMode false
}
}
