The commons-mass-description tool ran into this problem today. @Urbanecm was trying to start using `webservice --backend=kubernetes python start` and got the error message:
```
Looks like you already have another webservice running, with a gridengine backend
You should stop that webservice by issuing:
webservice --backend=gridengine stop
And then start it again with backend kubernetes by issuing:
webservice --backend=kubernetes start
```
`qstat` showed no process running at that instant, but `service.log` recorded `2017-04-19T17:13:22.646841 No running webservice job found, attempting to start it` and then a grid job spawned. This job died as soon as it started with this `uwsgi.log` output:
```

Set PythonHome to /data/project/commons-mass-description/www/python/venv
ImportError: No module named site
```
This error is caused by the `$HOME/www/python/venv` being built for Python3 on Kubernetes and the app being executed by Python2 on grid engine.
Multiple attempts to stop the grid engine webservice backend with `webservice stop` just printed `Your webservice is not running`. The `service.manifest` file however still contained:
```
# This file is used by toollabs infrastructure.
# Please do not edit manually at this time.
backend: gridengine
version: 2
web: uwsgi-python
```
Ultimately, using `rm service.manifest` stopped the `webservice` reconciliation loop from trying to restart the service on the job grid and allowed it to be started on kubernetes with `webservice --backend=kubernetes python start`.
