Hi !

I have Lighttpd and SCGI clusters running my applications. I  
self-host at RimuHosting, but I find that my processes die sometimes.  
I’m not a Linux administrator, so I simply want some kind of  
watchdogging process to ensure my stuff keeps on truckin’.

I found Watchdog::Process on CPAN, but it won’t install. There’s some  
kind of error. Launchd would be ideal, unfortunately, I’m on Debian.

Anyone has a good solution ? Maybe I should simply switch to FastCGI  
and let Lighty handle the details ?

Thanks !

Supervise your processes (lighty and the responders separately) using  
either daemontools or runit. See [http://www.defendem.com/](http://www.defendem.com/) for a  
sparse explanation but great installation instructions. We don’t use  
Debian so I can’t help you there.

I get an “Application Error (Rails)” ☹

```
Daedalus is a pure ruby daemon that monitors processes for you at

```

timed intervals and restarts them if they fail. I use it all the time  
and it works great.
