I've got something running on my webserver that is causing apache threads to stay alive. I'd like to find what site is causing the problem. For example, when I restart apache, it fails because there's a bunch of threads that haven't died. I have to get all the apache threads still running (ps aux|grep httpd) then manually kill each process listed. I'd like to find out what website or web call is associated with each of these processes so I can figure out how to stop this problem. Is there a way, given an apache process id, what website called or created that process?
