Hi, sorry for the delay in getting to this. Unfortunately, we don't have enough information to reproduce this.

If you encounter this again, please let us know and provide a crashdump with:

sudo snap install juju-crashdump --classic --channel edge
juju-crashdump -a debug-layer -a config

That should include extra info that we're missing from the older field agent dump.
