Looks like IntegrationSuite.TestCancelIfNoInstanceType returns while it still has a PUT /arvados/v1/containers/zzzzz-dz642-queuedcontainer request in progress. If the PUT request runs after the /database/reset request, its side effect (cancelling the container) leaks into IntegrationSuite.TestGetLockUnlockCancel and causes the failure.

The problem is that an unsatisfiable container with state=Queued gets cancelled twice.

Update → addEnt → func1 → Lock → apiUpdate → addEnt → func1 → Cancel
                        → Cancel

The test exits after the first cancel succeeds, allowing the second cancel to happen later.
