I have a script which intermittently returns a white screen of death in firefox and Error 324 (net::ERR_EMPTY_RESPONSE): Unknown error. chrome.

When I try to access the script using a PHP HTTP client (like Zend_Http_Client), intermittently I get an exception (sorry I don't have the exact message on me at the moment).

I suspect a segfault. This is further buttressed by the lines in my error log that look like this: [Thu Mar 18 16:03:02 2010] [notice] child pid 845 exit signal Segmentation fault (11)

Now, I'm running RedHat, and I know that RedHat doesn't generate core dumps out-of-the-box. I followed the instructions here http://kbase.redhat.com/faq/docs/DOC-5353, but I'm not seeing any core dumps.

How do I generate a core dump?
