I have lightttpd running on linux server with 8 cpus. And I start fast cgi written in C total number of 16 processes. The problem to me now is that the lighttpd didn’t distribute the requests to different fastcgi process equally. For example, 15 of them, each get requests about 10 to 20. But another one process get requests more than 50000.

What is the problem and how to fix it and let each fastcgi process get equal requests?

Thanks
