Problem with 2.0-RELEASE (amd64), 100% CPU

[crahier]

Hi,

A few weeks ago, I installed pfsense v2.0-RC1 and upgraded to new versions.

Actually, I use 2.0-RELEASE (amd64). This software is installed on a VMware with 6 CPU and 4 Gb RAM.

Today, all processor where used at 100% of process and I had to restart the server.

It's the first time I've this problem but I don't know how I can fix this problem.

Many thanks to help me, I'm lost :-(

you should take a look at "DIAGNOSTICS -> SYSTEM ACTIVITY" and tell us which processes are using all the CPU power.

But at this time, I couldn't connect to the firewall.

Actually, here's what I could see :

All CPU are idle. Thats ok.

Can you connect to your pfsense box using ssh when there is such a high CPU load ?

If yes, than connect to your box and type "top" in the console and then you can see which process is using so much CPU power.

But what were you doing when you get this high CPU usage ?
Are you using any packages ?

Hi,

Thanks for your feedback.

I didn't think to try to connect with ssh. I tried to connect to the VPN but it was not possible.

When the problem occured, nothing special. I looked at Cacti but the trafic was very quiet.

It's very strange because this load was very fast (sorry for my poor English).

No other packages installed.
