Comment 4 for bug 1858693

I got hold of the lease snapshots from IS, they look like this:

Earlier snapshot (taken at 2020-01-08T21:59:54.560)

global-time: 0001-11-28T14:46:13.032021499Z
entries:
...
  ? namespace: application-leadership
    model-uuid: e951cb4a-9abf-420a-8ee0-4dcc7716dbe9
    lease: canonical-livepatch
  : holder: canonical-livepatch/1816
    start: 0001-11-28T14:46:00.03012772Z
    duration: 1m0s

Later snapshot (taken at 2020-01-08T22:03:08.582)

global-time: 0001-11-28T14:49:14.156856294Z
entries:
...
  ? namespace: application-leadership
    model-uuid: e951cb4a-9abf-420a-8ee0-4dcc7716dbe9
    lease: canonical-livepatch
  : holder: canonical-livepatch/1816
    start: 0001-11-28T14:48:47.148564464Z
    duration: 1m0s

That makes it looks like the canonical-livepatch/1816 agent was still running and renewing its lease - there's nothing else that would be updating the start time like that.

So it seems like the bug is more likely to be with unit teardown somehow?
