Comment 1 for bug 1598964

I suspect this is due to how we synchronized hooks / juju-run. The fix for bug 1486712 changed the locking mechanism used, and this may fix the problem.

Previously, a killed process wouldn't relinquish the lock. But the new implementation shouldn't have that problem.

Once 1.25.6 is released (hopefully soon), could you retest to see if the problem persists?
