Hi,
I am running a Rails app on Dreamhost, which has what I think is a
fairly standard Apache/Mysql/Fcgi setup.
My app hung this morning after several days of event-free operation...
there was nothing that showed up in the production log. The app was
just failing to respond. I tried restarting it once, which didn''t seem
to work... When trying to access it from my browser, I got the "Rails
application failed to start" page. I restarted it again and it came
back up.
The problem may not have anything to do with fcgi, but I looked at the
fastcgi.crash.log and saw ominous messages, does this exception mean
anything to anyone? Any suggestion of what happened here and how I can
prevent future issues?
Best,
Eric

The meat of my dispatch.fcgi looks like this ... I basically stole this
from a Dreamhost posting. I don''t pretend to understand how it works.

end
end
RailsFCGIHandler.process!
