I’m running Ruby on Rails on Fedora Core 4 with lighttpd and fastcgi. I  
also used the login generator (don’t know if relevant). I have the  
following problem: At day time I work on the server and create/modify  
ruby files on the server, all pages work fine. Than the next day I want  
to open de server I get the error at the end of this message (on all  
pages, including non protected).

If I restart lighttpd everything works again. Any ideas on how to fix  
this? This happens every day…

Thanks,

Stephan

I had a similar problem under Apache and FastCGI. The MySQL connection  
would time out after a few hours of inactivity, but Rails would not let  
go of it. The next time I tried to hit a page, I would get an error  
like yours. I fixed it by increasing the MySQL timeout and by  
decreasing the amount of time the FastCGI processes hang around.

Hope that helps!
