ID: 14333 Updated by: sniper Reported By: [EMAIL PROTECTED] Old Status: Open Status: Feedback Bug Type: Apache related Operating System: RH 6.2 SMP PHP Version: 4.0.6 New Comment:
I'm also running PHP / Apache in a SMP machine but I never have noticed anything like this. Some things we need to know about your system: - Kernel/glibc version - Apache version - PHP configure line And you should also try with PHP 4.1.0RC5: http://www.php.net/~zeev/php-4.1.0RC5.tar.gz --Jani p.s. This might sound stupid but did you do './apachectl stop ; ./apachectl start' or did you use './apachectl restart' ? Previous Comments: ------------------------------------------------------------------------ [2001-12-03 19:35:22] [EMAIL PROTECTED] Actually, there is a sample PHP script installed on the server in several user directories. But this is the ONLY file with a *.php* extension within our web root directories. It is called "hello.php3" and it looks like this: <html><head><title>PHP Test</title></head> <body> <?php echo "Hello World<P>"; ?> </body></html> I really don't think this script is being run. I don't think that any script is being run to cause the problem. Thanks, Tauren ------------------------------------------------------------------------ [2001-12-03 19:21:39] [EMAIL PROTECTED] I've been experiencing the exact same problem that is described in bug #14290 and #8446 for quite some time now but did not know which Apache module was causing it. Up until now, I've had a cron job that simply kills off (with a -9) any httpd processes that are using 99% or more cpu time. Today I've been trying to track down what exactly is causing the problem. I've eliminated all extra Apache modules and did not experience the problem. When I added PHP back in, the problem started immediately. Within one minute of starting Apache back up, the high-CPU processes started appearing again. The Apache "server-status" didn't indicate that ANY php script had been hit. The processes just start going out of control after some time. In fact, there isn't even a single *.php* file on the server. I really don't think this is happening because of a PHP script being run. I'm currently testing this out on a Red Hat 6.2 Linux (SMP) box with dual CPUs. From the sound of things in the other bug reports (#14290 and #8446), the problem only seems to be happening on SMP servers. I did not compile with any extra PHP modules except for the core PHP 4.0.6. I haven't really done a lot with PHP, so I'm not sure how to help debug this problem. But I do want a stable Apache environment with PHP support for my hosting customers. If there is anything I can do to help debug things, please let me know. I've read the page on using gdb, but I'm think this is a different kind of situation. Apache isn't crashing, but certain processes are going "out-of-control". Is there a way to get a backtrace of a particular process while it is still running? Until this problem can be resolved, I'm going to have to remove PHP from my servers. I really don't want to have to do this, but the instabilities are becoming too much to handle and very hard to explain to our customers. Please let me know what I can do to help debug and solve this problem. Thanks!
