On a RAQ4i I want to figure out what a runaway httpd process was actually trying to serve, in order to locate what I believe is a "bad" PHP script. All I can get is the httpd PID # for the offending instance.

Currently, if the process that seems to cause problems any given day isn't killed quickly enough the server stops responding. PHP scripts are the only scripts, outside of SSI, that I have seen come up with only httpd running, when using top, and therefore I want to figure out what it is that is causing the trouble so that it can be taken out.

I can identify the PID using top, as the process CPU usage goes way up and stays there for 10-15 minutes before the RAQ goes unresponsive, causing the RAQ to slow down considerably.

Does anyone have any ideas?
