thank you all!
I’m indeed running v212.
Deleting /var/vcap/store/shared/run.10.10.2.37.xip.io-cc-droplets/buildpack_cache
did the trick.

cf-release v213 fixed a bug where buildpack caches were not getting cleaned up properly. Are you running a version prior to 213?

If so, you might need to go into the `shared/run.10.10.2.37.xip.io-cc-droplets` directory and delete the `buildpack_cache` subdirectory. Deleting the contents of buildpack_cache will not cause failures in the system, the caches will simply get generated from scratch the next time apps stage.

If you upgrade to 213 or later, you can just call the api endpoint to clean out the buildpack cache. You can find the details in the v213 release notes:

Droplets are important, and should not be removed. If an app is deleted,
the droplet will also be deleted. If a droplet exists, that means it is
still needed.

If the app needs to be scaled up or moved to a different runner, the
droplet is reused. In theory droplets could be recreated from the package
if it were deleted, but there is no automated behavior for this. You would
need to `restage` the app to force the system to generate a new droplet
from the existing package.

Droplets and app packages should be pruned when the applications they're
associated with are deleted. Only one or two versions of the droplet are
ever held and only copy of the application bits.

There's another blob store that holds application resources for resource
match flow when uploading an app. Those resources are not pruned so you
should make sure that you disable that in your manifest if you don't want
that behavior.

The droplet blob store is clearly your issue - not events.

Just a thought: How large is your events table? Is it getting pruned at the
correct interval for you?

I believe events, app usage events, and audit events are pruned when
they're more than 31 days old default. You could change the cc properties
in the deployment manifest to make that a little more aggressive if that's
the problem.
