I have puppet master
running on a Xen dom0, and 3 domUs syncing to it via an hourly crontab puppet agent --test
.
About 80% of the time, the puppet agent --test
completes successfully:
info: Retrieving plugin
info: Caching catalog for test3
info: Applying configuration version '1333319732'
notice: Finished catalog run in 5.08 seconds
The other 20% of the time, it fails midway, with errors such as the following:
err: Could not retrieve catalog from remote server: Error 400 on SERVER:
Could not find class iptables for test1 at /etc/puppet/manifests/site.pp:1 on node test1
warning: Not using cache on failed catalog
err: Could not retrieve catalog; skipping run
or
info: Retrieving plugin
info: Caching catalog for test2
info: Applying configuration version '1333319732'
notice: Finished catalog run in 24.73 seconds
err: Could not send report: Error 500 on SERVER:

During this time, I've not made any changes to the Puppet configuration — it just sporadically fails.
I'm running puppet-2.7.12 on CentOS, and followed the setup instructions described on http://docs.puppetlabs.com/learning/agent_master_basic.html.
Any ideas about how I can troubleshoot this?
