I noticed this whilst debugging D11351. Basically, I was trying to start the Aphlict server but the log file didn't exist. Something like this was happening:
```
> ./bin/aphlict start
> ./bin/aphlict status
Aphlict server is running.
> ps aux | grep aphlict
... php /usr/src/phabricator/bin/aphlict start
# No NodeJS process running
```
The NodeJS aphlict server died, but the PHP process was still alive.
