FCGI cause Error 500 under high load

[Wut]

Hi All,

I found several post about this in German corner but I can't understand it so I ask again here.

My server often got Internal Server Error 500 under high load.

In /var/log/apache2/user/{domain}-error.log I found

[Thu Oct 30 11:01:23 2008] [error] [client {ip}] (4)Interrupted system call: FastCGI: comm with se
rver "/var/www/fcgi/{domain}/php5-fcgi-starter" aborted: select() failed
[Thu Oct 30 11:01:23 2008] [error] [client {ip}] FastCGI: incomplete headers (0 bytes) received fr
om server "/var/www/fcgi/{domain}/php5-fcgi-starter"

This problem doesn't occur so much (about 3-4 times per hour) but I just want to know if there is any solution ?

I also found this

But I don't know how to patch it

Any suggestion ?
