Re: puppet-agent-6.25.0 breaks puppetserver-6.17.0 with multithreading enabled I think this is related to, possibly duplicates PUP-10958. Puppet 6.25.0 had a few changes relating to environments and their loaders. See PUP-11158 and PUP-10955.

Sorry Chris Fox I meant 6.25.0. You'll need to install the openjdk devel package (that provides jstack), then once the server hangs, execute something like: $ sudo -u puppet /path/to/jstack -e -l `sudo pgrep -F /var/run/puppetlabs/puppetserver/puppetserver.pid`

Re: puppet-agent-6.25.0 breaks puppetserver-6.17.0 with multithreading enabled I've been seeing a lot of these "Attempt to redefine loader" errors shortly after puppetserver has started and is taking some agent traffic. The errors go away after being thrown 1-3 times. stacktrace-attempt_to_redefine_loader.txt My Puppetserver host is using: puppet-agent-7.14.0-1.el7.x86_64 puppetserver-7.6.0-1.el7.noarch Attached is a stack trace from one such error. stacktrace-attempt_to_redefine_loader.txt

FYI this same issue (redefine loader) occurs on server 7.x when the 7.14 agent is instealled: SERVER-3160 which seems caused by this change in the 7.14 agent: PUP-11373.
