Server load 120 ???

[Devanand]

My site is down and load is 513 omg.
I got over 100 of emails for msql database error like this:

Database error in vBulletin 3.8.2:

Invalid SQL:

My provider said that I am geting more traffic than I can get but I had onlt 50-60 people few minutes before crash and I am on dedicated server.
All this email look same, only that IP at the and are different.
Does anyone know what can be problem?
Is msql demage or what?

You need to repair your guest table. You may have to ask your host for help with this.

Also, there is no 'guest' table in default vbulletin - the table is from a mod, so perhaps you want to try turning off that modification.

I was DDOS and it is still running. My host told put some sowtware firewall but it can't stop it. They said they can put dedisated hardware firewall but it will cost me $129/month .
What is your suggestion, what to do?
How to protect from this kind of attacks?

Unless this happens all the time to you, you might want to save the $129/month and wait it out.

There are other threads about this very subject. You may want to do a search on it and read up on what other people do.
