I recently created a rails 3.0.5 app, and it appears that this line was added to my crontab:

8,28,48 * * * * /home/<user>/webapps/<app>/bin/start

As a result, I get emails every 20 minutes with the following errors, presumably because it's trying to start an nginx instance that's already running:

[emerg]: bind() to failed (98: Address already in use)
[emerg]: bind() to failed (98: Address already in use)
[emerg]: bind() to failed (98: Address already in use)
[emerg]: bind() to failed (98: Address already in use)
[emerg]: bind() to failed (98: Address already in use)
[emerg]: still could not bind()

I changed the line in my crontab to run restart instead of start, but I'm not sure whether it's even necessary. Should I just delete it?

You should not remove as it is meant to restart your in case its nor unning. You can instead redirect its output to /dev/null by adding "> /dev/null 2>&1"

@neeravk isn't it better to run restart then, since it's most likely already running? I've never seen this on an nginx installation before.

[Edit] Using restart is fine. However, it will terminate active sessions, so redirecting the output to /dev/null will allow this to fail silently as expected.
