skaffold dev does not show live tail logs after running for a while

### Expected behavior
running `skaffold dev` should live tail logs after running for a while
### Actual behavior
After multiple image rebuilds and changes to source code, I don't get live logs when the server receives HTTP requests.
### Information

- Skaffold version: 0b8bd59
- Operating system: macOS Catalina - version 10.15.5
- Contents of skaffold.yaml:

```

Here's the k8 deployment for the pod that does not live tail
```yaml
apiVersion: apps/v1
kind: Deployment

name: api
namespace: kludge

- name: APP_LOG_LEVEL

value: "mysql"
- name: DB_DATABASE
value: "kludgedb"

```

### Steps to reproduce the behavior
Running `skaffold dev` but usually after 2 days or so live tail logs does not work, but the cluster is still running and everything else works.
