At first we suspected that it due to multiple clients trying to register at the same time, but then when I tried to register only 1 client, again I got this error s.

Output Example :

Dominic, googling this error looked like it was related to timeouts, any ideas or experience with this?

Can we get logs with timestamps perhaps (from syslog)?

I encountered the same problem. Attaching the syslog.

Thanks.  The Puppet agent is timing out while fetching plugins, which is controlled by the "configtimeout" setting in puppet.conf (defaults to 2 minutes, and is overloaded in what it claims to do).

There are a lot of plugins in this OpenStack setup, but IMO the rate at which the client is downloading them is rather slow, so I'd ensure that your puppetmaster has enough RAM and both the puppetmaster and agent have reasonable I/O performance so they can read + write the plugins to disk.

The foreman_client.sh script could increase the configtimeout setting to 5m or similar in puppet.conf to workaround the issue.  A bug could also be filed against Puppet to add a new setting to control the pluginsync timeout separately from the configtimeout, and for it to be higher by default.

Is this still an issue?

There has been no report of this issue in months, I am closing as not a bug, since we made no changes.  If the issue recurs, feel free to reopen this.

closed, no need for needinfo.
