That would've been my first shot (if on RHEL 5 that value is higher, or 0, consider changing it: http://httpd.apache.org/docs/2.2/mpm.html ) Next off is that you should consider running PHP accelerated. See: http://pecl.php.net/APC Also, your application is also a good candidate for memory consumption. Take a look at my writeup on that topic: http://blag.esotericsystems.at/2010/01/php-memory-abuse/ > Best Regards, > Arun J So long, -- Igor Galić Tel: +43 (0) 699 122 96 338 Fax: +43(0) 1 91 333 41 Mail: i.ga...@brainsware.org URL: http://brainsware.org/ --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
