Server crash when FCKeditor start

Hy,

i have a big problem.
First, i tell you, that the FCKeditor is running perfectly in localhost @ WinXP pro and XAMPP (apachefriend) solution.

Now i changed the page to the finally webserver (Linux) and now i have a big problem and did not find the error.

When i start the FCKeditor, then the server crash for 5 minutes (i cant remote this server!) when the server crash, i can´t connect to the website, i can´t connect to the ftp, i can´t connect to nothing on this server.

i guess, the server will be overloaded, when i start the FCKeditor.

What do you mean, can it be? or better, do you have a solution for me?

Sorry i´m german, my english is not the best... Maybe german people can email me, or english members write here...

Thanks a lot
Clamsy
