I have Red Hat 6 and I've installed Lighttpd + MySQL and at the moment in getting 500 internal server error, logs shows that I have arround 2000 requests / sec, while as soon as requests drop below 1000 websites starts to load again.
I wonder how can I increase this limit.
My machine have 20 CPU's, 128GB RAM, so I doubt it's machine problem :S
I use FastCGI, while website is in PHP language.
