> Destroying container 1e5b8fc3-5c9e-4159-a0b9-3d46595a5b54 in ISOLATING state
> {code}
> In the above logs, the state of container
> `1e5b8fc3-5c9e-4159-a0b9-3d46595a5b54` was transitioned to `ISOLATING` at
> 09:13:23, but did not transitioned to any other states until it was destroyed
> due to the executor registration timeout (10 mins). And the destroy can never
> complete since it needs to wait for the container to finish isolating.
