The problem
I created a process using PHP to work with Nginx like this:
@echo off
echo Starting PHP FastCGI...
set PATH=C:\nginx\php;%PATH%
C:\nginx\php\php-cgi.exe -b 127.0.0.1:9000 -c C:\nginx\php\php.ini
pause
But if more than 500 requests occur simultaneously this process is terminated and does not send any failure message or anything like that. Note that the Ngnix process continues to work, only PHP stops "working".
To be more clear, this problem occurs when I use the ab to test the performance of pages on an "ngnix" server in this way:
ab -n 1000 -c 10 http://127.0.0.1:8000/info.php
After executing the ab, I have the following results:
Completed 100 requests
Completed 200 requests
Completed 300 requests
Completed 400 requests
Completed 500 requests
apr_pollset_poll: The timeout specified has expired (70007)
Total of 503 requests completed
Then I will check the PHP process on the "CMD" screen and it is with the following message:
Starting PHP FastCGI...
Pressione qualquer tecla para continuar. . .
Clearly "CMD" went to "PAUSE" because the PHP process is over.
What might be going on?
Follow my settings:
- Ngnix 1.6.2
- PHP 5.4.12
