So I've installed WordPress 3.2.1, installed Tisa from Themify.me (http://themify.me/themes/tisa), and I've run into some problems. When viewing the page, the images only show up half the time. This seems to be the server running out of memory - this line shows up in my error logs:
[error] [client 22.214.171.124] (12)Cannot allocate memory: couldn't create child process: /opt/suphp/sbin/suphp for /home/verdant/public_html/wp/wp-content/themes/tisa/themify/timthumb.php, referer: http://wp.verdant.com.au/
So it appears to be the image resizing component (which, as I understand it, is pretty damn common with WP blogs), and a theme, are maxing out the server. This seems pretty weird - they support 64M PHP limits, and aren't too stingy - I've got 1 GB of available memory. So how is WP maxing it out? What can I do to profile/optimize it? Must admit, one of the biggest challenges I've found approaching this is how to profile and figure out where all the memory is going...
Cheers for any help. Website is http://wp.verdant.com.au if you want to have a look for yourself.
