Issue #19153 has been updated by Charlie Sharpsteen.
Alright, first let's double check that it is the cron jobs and not a respawned
daemon that is getting killed off since both will emit messages to the syslog
of the form:
puppet-agent[<pid>]: Caught TERM; calling stop
So, if you could temporarily redirect the agent's log to somewhere other than
the syslog when running under cron:
* * * * * puppet agent --onetime --no-daemonize --logdest
/tmp/puppet-cron.log
and tell me if the kills are showing up in `/tmp/puppet-cron.log`.

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.
