Hello

Since I’ve updated from rc3 to rc4, I only have one rails app that  
doesn’t render anymore. In fact, it doesn’t run anymore.

- Development.log is empty,
- 10 fcgi processes are running (already tried to restart them with  
./script/process/reaper , and lighttpd in rc.d)
- lighttpd log confirms #200 requests.
- dispatch.fcgi has still the -rwxr-xr-x rights.

What could be wrong ? I don’t know where to look at.

Thanks for your help

One thing that’s bitten me is that Rails RC4 doesn’t appear to warn  
you if your session contains objects that it cannot load back into  
memory (for instance, if you have changed the Model in some way, or  
have errant DBI connections stored in there…). In olden days you  
used to get an error message, but at the moment you get a nothing in  
any logs, rendered, and only the slightest hint of an error in the  
form of a 500 response indication from WEBrick’s console.

So - one thing to try might be ensuring that you’ve cleared out all of  
your session objects.

If you are 'require’ing a file that doesn’t exist or has  
bad permissions the app wont start, and no log message.

That’s too bad.  
And I found why it bugged: the mysql user had no permission and only  
scripts/console told me.

Why these errors are not raised in development.log ?
