Hi all,  
I tried porting over the default Photos app from RoR: up and running, to  
my VPS hosted environemnt. I finally got everything up and running on  
apache, and the app worked for a few days with no problems. Then,  
yesterday, I started getting Application Error (Rails) whenever I would  
go to the slideshow mode of the project. This persisted until I cleared  
my mysql database and reloaded the data from scratch. This leads me to  
believe it was a problem with some of the mysql data, but I cannot  
confirm this. Is there any way to easily check which piece of data was  
causing the problem? Note that the logs did not tell me anything. Any  
way to tweak/configure mysql to avoid this in the future?  
Thanks,  
Brian

the logs must have said _something_, even if it seemed meaningless at  
the time…  
can you send the log entry for the failure?

Hi Dorian,  
Honestly, the logs said nothing relevant. I hear things are logged much  
less in production mode, but there was nothing in them…
