I've tried looking on the forums for this question, and nobody has responded to my query (all other forum topics on the subject have solutions that do not work). I am running the latest stable version (2.7) and my wp-admin/index.php occasionally fails to load, and apache reports a segmentation fault. I say "occasionally" because it decides to do this at seemingly random moments, but these moments last several minutes. It happened again about 10 minutes ago, and now the page is loading perfectly.
First, there's no way for WordPress, in and of itself, to cause a segmentation fault on the machine. The root of the problem is going to lie somewhere in a system binary (PHP, apache, a php or apache extension, or system library). That said, it could be that some particular bit of PHP code in WordPress, a theme, or plugin could be triggering whatever condition that is related to the segfault. It could be due to exhaustion of memory or some other resource, or it could just be a buggy third-party PHP extension.
You should probably carefully check your PHP and Apache configuration. Make sure you aren't loading any extra modules that aren't absolutely needed. Disabling your WP plugins one at a time, and monitoring the segfaults might possibly help you narrow down what's causing it. For example, if you have a plugin that does manipulation of graphics, and disabling it makes the problem go away, then you might have a buggy version of the GD or Image Magick libraries?
