This will definately address the memory leak issue although is more of a bandaid than a real fix. 1000 for the MaxRequestsPerChild setting is a good starting point but may need to be adjusted up or down as you watch the memory usage of Apache processes. If you're looking for more performance, I highly recommend using a PHP accelerator, I've had great luck with PHP Acclerator at http://www.php-accelerator.co.uk/ and it's free. It significantly increases the responsiveness of SM. Not being a real PHP hacker, I can't say what steps to take to diagnose the cause of the memory leak and I don't run SM on any high usage sites. -Dave ------------------------------------------------------- This SF.net email is sponsored by: ValueWeb: Dedicated Hosting for just $79/mo with 500 GB of bandwidth!
