Propolis panic during zone uninstall

I found two sets of propolis core files on a certain sled after running the "parking" script that halted and uninstalled all zones on the sled.

Here are the core files of two specific propolis zones - there are 5 occurrences for each of them:

The stacks appear identical and here is one of them:
