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.
