I recently have been getting 503 errors on a wordpress site - it only
happens on this certain site running wordpress (all other PHP, non
wordpress sites work). I even uploaded a phpinfo file to the wordpress site and that displays fine. As for the 503 errors, error log shows entries like so:

It only started recently, but it sounds like something in lsws is
conflicting with wordpress? Any ideas?

It is a problem with your PHP, maybe you upgrade php recently.
you can try strace the PHP process for that user account.

Nothing has been changed recently PHP configuration + LSWS configuration wise. We are using PHP 5.2.9 + LSWS 4.0.3. Are you saying it is a PHP config issue or rather something wrong with the actual script?

Yep, it is an actual script issue. Removing all wordpress plugins allows the site to load without error. Time to find out which plugin exactly is causing the issue, then troubleshoot further from there.

That's the right approach.
