Bug 769842

Description of problem:
On system's operation sometimes cobbler is detected as stopped, so it's launched again.

After this happens, cobbler no longer works

Version-Release number of selected component (if applicable):
cobbler-2.0.11-2.el5 and cobbler-2.0.11-2.el6

How reproducible:

[root@satellite ~]# cobbler check
The following are potential configuration items that you may want to fix:

1 : you need to set some SELinux content rules to ensure cobbler serves content correctly in your SELinux environment, run the following: /usr/sbin/semanage fcontext -a -t public_content_t "/var/lib/tftpboot/.*" && /usr/sbin/semanage fcontext -a -t public_content_t "/var/www/cobbler/images/.*"
2 : you need to set some SELinux rules if you want to use cobbler-web (an optional package), run the following: /usr/sbin/semanage fcontext -a -t httpd_sys_content_rw_t "/var/lib/cobbler/webui_sessions/.*"
3 : some network boot-loaders are missing from /var/lib/cobbler/loaders, you may run 'cobbler get-loaders' to download them, or, if you only want to handle x86/x86_64 netbooting, you may ensure that you have installed a *recent* version of the syslinux package installed and can ignore this message entirely.  Files in this directory, should you want to support all architectures, should include pxelinux.0, menu.c32, elilo.efi, and yaboot. The 'cobbler get-loaders' command is the easiest way to resolve these requirements.
4 : change 'disable' to 'no' in /etc/xinetd.d/rsync
5 : debmirror package is not installed, it will be required to manage debian deployments and repositories
6 : The default password used by the sample templates for newly installed machines (default_password_crypted in /etc/cobbler/settings) is still set to 'cobbler' and should be changed, try: "openssl passwd -1 -salt 'random-phrase-here' 'your-password-here'" to generate new one
7 : fencing tools were not found, and are required to use the (optional) power management features. install cman or fence-agents to use them

Restart cobblerd and then run 'cobbler sync' to apply changes.

###################### FIXED AFTER RESTART ^


Expected results:
Cobbler start shouldn't start it again if it's already running. From the python message, it looks like a authentication problem from CLI after a new cobbler is started.
