Hey Ryan,
At first glance this sounds like
https://tickets.puppetlabs.com/browse/PDB-2390, but that was fixed in
4.0.0 so it shouldn't be the issue. The fact that you have 2 gigs under
discarded means you are sending a significant number of commands that
PuppetDB is unable to accept. There are numerous reasons this can happen
-- you'll probably find more info in your logs. Given that you have so
many discards, it could be that the bloat in your scheduler directory is
actually legitimate (malformed commands get retried, and while being
retried they go to scheduler.
My suggestion would be to look at your PuppetDB logs and/or the files
under discard (these will have errors in addition to the actual message)
to figure out the problem. Post back with the errors if need be and we
can trouble shoot from there.

I'm using puppetdb-4.0.0-1.el7 (open source) and over time the
ActiveMQ part of it has been saving a bunch of logs
under /opt/puppetlabs/server/data/puppetdb/mq, and there does not
appear to be any built-in log rotation, at least in the version I am
using. After using this puppetdb a couple months, this is the sizing I
observe:
* 6.5GB = /opt/puppetlabs/server/data/puppetdb/mq/localhost/scheduler
* 2GB = /opt/puppetlabs/server/data/puppetdb/mq/discard
The only solution I found online is
this: https://docs.puppet.com/puppetdb/4.2/trouble_kahadb_corruption.html.
The workaround there is to rename the mq directory and restart
puppetdb, but it is intended as a troubleshoot, and I am seeking to
save disk space and avoid regular puppetdb restarts.
What files are safe to delete? Is this still a problem if I upgrade to
puppetdb 4.2?
