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?

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,
Marcus

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.
