ID: 28065 Updated by: [EMAIL PROTECTED] Reported By: floeff at arcor dot de -Status: Open +Status: Bogus Bug Type: Reproducible crash Operating System: Linux 2.4.26 PHP Version: 4.3.6 New Comment:
1. Don't run Apache 2 2. Don't run PHP as CGI Do use apache 1.3 with the apache SAPI and this works fine; apache 2 is NOT ready for production. Previous Comments: ------------------------------------------------------------------------ [2004-04-21 21:36:55] floeff at arcor dot de I checked some more things, here some more results: - On my test machine, I've set MaxClients in httpd.conf to 20 and I couldn't kill the machine anymore. This is only a workaround, as it knocks out a lot of users on higher load machines, but at least it shows that MaxClients works for that. - When a "normal access" (i.e. not my "attack") accesses a PHP script, the PHP parser is only shown during the run of the script, checked with ps auxw | grep php. However, when I "attack", it runs for quite a while several times. It does seem to use the 300 seconds timeout, as I lowered this to 10 seconds, and the scripts got killed with "(70007)The timeout specified has expired: ap_content_length_filter: apr_bucket_read() failed". However, it does not help to lower it, the load rises even more. Had about 97 (!) some seconds ago :-( "killall php" or "killall -9 php" doesn't help. However, shutting down Apache brings down the PHP interpreters, so I think that Apache just "forgets" about the running instances when it is flooded and cannot handle them anymore. Do you have any idea? Do you need more information? ------------------------------------------------------------------------ [2004-04-20 19:05:25] floeff at arcor dot de If PHP does not terminate after the set amount of time, then for me it is a bug. Why shouldn't it be one? ------------------------------------------------------------------------ [2004-04-19 23:23:34] [EMAIL PROTECTED] Sorry, but your problem does not imply a bug in PHP itself. For a list of more appropriate places to ask for help using PHP, please visit http://www.php.net/support.php as this bug system is not the appropriate forum for asking support questions. Thank you for your interest in PHP. . ------------------------------------------------------------------------ [2004-04-19 19:49:35] floeff at arcor dot de Description: ------------ Maybe I misunderstand something, but for me it seems that the resource limits do not work. In my php.ini, I set max_execution_time = 10 max_input_time = 10 which - to my understanding - should limit executing time for scripts to 10 seconds. I have PHP running as CGI with Apache 2.0.49 on Linux 2.4.26 here, and with a hughe PHP file involving some diagram creation, I can kill the machine if I re-load the script for five seconds continuously. It soaks up all my memory and runs for nearly a minute. What could be wrong in here? If you need more information, please let me know. Thanks! ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=28065&edit=1
