Doc Type: Bug Fix
Doc Text:
Cause: Executing "killall httpd" command to terminate an HTTP daemon provided by httpd24-httpd package when mod_perl Apache module is in use. Consequence: The command cannot find the daemon process. Fix: The daemon was changed to set zeroth argument to its short name "httpd", so it is listed under this name in a process listing. Result: Its possible to terminate httpd process running a Red Hat Software Collection's mod_perl by the "killall httpd" command.

Description Ondřej Pták 2015-01-21 16:01:38 UTC 
Description of problem:
When service httpd24-httpd is running, httpd processes have bad command name in /proc/PID/comm and so "killall httpd" doesn't work

Version-Release number of selected component (if applicable):
httpd24-httpd-2.4.6-22.el6.x86_64

How reproducible:
always

Steps to Reproduce:
1. service httpd24-httpd start
2. ps -e|grep httpd

Actual results:
processes has name: /opt/rh/httpd24


Expected results:
processes should have name: httpd

Additional info:
1) "killall /opt/rh/httpd24/root/usr/sbin/httpd" does work
2) this problem is only with httpd24 on RHEL-6, systems's httpd is OK, httpd24@RHEL-7 is also OK
Comment 2 Joe Orton 2015-01-27 13:08:33 UTC 
jkaluza says this is a mod_perl bug, similar to bug 782369.  We can attempt to resolve in perl520's mod_perl.
