Issue #19153 has been updated by R.I. Pienaar.
Charlie, the problem here is that mcollective does basically "puppet agent
--daemonize --onetime" which will create all the various locks and pids like
the daemon started by the rc system. So when you then do service{"puppet":
ensure => stopped} that will stop the daemon that mcollective started instead
of only daemons started by the init script
You can easily reproduce this:
<pre>
# service puppet status ;puppet agent --onetime --daemonize;service puppet
status; sleep 1; service puppet stop
puppet is stopped
puppet (pid 14892) is running...
Stopping puppet agent: [ OK ]
# tail -n 1 /var/log/messages
Mar 1 21:32:06 localhost puppet-agent[14892]: Caught TERM; calling stop
</pre>
So the problem is the rc script does not distinguish between a daemon started
manually and one started by the rc system.

Bug #19153: service puppet ensure stopped kills off cron-run puppet with
"Caught TERM; calling stop"

We have recently switched from puppet agent in daemon mode (for kick) to
cron-run puppet with mcollective agent. However, I started noticing that puppet
policies were being inconsistently applied across the hosts. It turns out that
this policy is the problem:
<pre>
service { 'puppet':
ensure => stopped,
enable => false,
require => File['/etc/cron.d/puppet','/etc/puppet/puppet.conf'],
}
</pre>
I have checked and confirmed that the puppet init script returns the correct
response even when puppet is running. If I run "puppet agent --test" in one
window and while it is running I run this in the other window, it shows clear:
<pre>
root@sj2-noc01 ~$ service puppet status ; echo $?
puppet is stopped
3
</pre>
However, if I run puppet in a silent mode with --onetime and --no-daemon then
the init script returns this value
<pre>
root@sj2-noc01 ~$ service puppet status ; echo $?
puppet (pid 30406) is running...
0
</pre>
This causes it to kill itself off, and not finish the run. Due to the
semi-random nature of ordering, this happens near the end or near the beginning
of the puppet run on different hosts. (there are few dependancies on the puppet
module, so its order in the manifest is random from host to host)
This is clearly a major flaw. We need the above policy to ensure that no puppet
daemons are running, however it interferes with the cron-run instance. However
it is handled properly when run verbosely with test.
Environment is a mixture of CentOS 5 & 6.
