Apache processes running for long times?

I'm not sure if this is a XOOPs problem or not, but if it isn't hopefully there are some apache gurus here that can help :)

My site (running XOOPs 2.0.5.1 with some modifications, and the IPBoard module integrated by Koudanshi v1.23) has apache processes running for very long time periods - some are still running for over 6 hours! The processes are still using CPU time so the performance of the site gets worse and worse. I've talked to my host about it and they're not sure, the only solution they could offer for now is to reboot the webserver once a day to kill off the processes.

Any ideas what would be causing these processes to be running for so long?

Re: Apache processes running for long times?

So many reasons that could be the cause. Your set-up is out of date and modified enough to be a possible problem and not XOOPS specific.

You should check what the server is running. A PHP file with:
<?php phpinfo(); ?>

might tell you more of the story. first thing to check besides the versions is if PHP is running as CGI or Module. A CGI PHP can eat a lot of processes.

You said "reboot" the web server? Is that a Windoze server? If that is the fix than you have all kinds of problems at the box.

By "reboot the webserver" I meant shut down and restart apache, sorry. And it's a Linux server.

I keep meaning to update the XOOPs core but it's a pain when I've done modifications to get it looking & behaving exactly how I want it to :(

Under 'Loaded Modules' in the apache section of phpinfo it has mod_php4 so I assume PHP is running as a module?

Check the line near the top "Server API" . Does it say "Apache xxx Handler" or "CGI"?

Versions of Apache, PHP, MySQL, MySQl libraries, etc might help.

Is there some way to see what pages are being served/still being served by an apache process so I can narrow down what page(s) are causing the problem?

Found the problem, I had some code that was opening a 2nd connection to the DB - this seemed to be killing the webserver.
