Hi all,

I am new to PHP and to this forum.

I was testing my webserver with PHP and found out that after 500 
requests the php-cgi process finished (without cores). I ran it with 
valgrind and no memory leaks :). I thought it couldn't be a coincidence 
that, always, after 500 requests, php-cgi finished; so I have had a look 
at cgi_main.c and found:

max_requests = 500;

I have seen that the environment variable: PHP_FCGI_MAX_REQUESTS might
be used to override this value; why php-cgi has to finish after n requests?

Thanks in advance,

Guido.

It is a common habit to reload the binary after a given number of requests.
This prevents memory leaks and other esource issues.

Best regards,

Hi Marcus,

thank you very much for your response. I have set the environment 
variable to a big number and test with valgrind and everything seems to 
be fine (no leaks), so before launching php-cgi, I will always set this 
variable :).


Guido.
