Hello guys, I’m developing a new app in Rails, and every now and then  
I get an ActiveRecord error, I cannot reproduce exactly what triggers  
it, hope you can help me, or give me tips on debugging this kind of  
stuff. This time I got the error reporting page, but normally I would  
just see the 500.html page, with no info about what went wrong.

This is the error (it’s the complete text from the error page):

===============================================================  
ActiveRecord::StatementInvalid in ShopController#new\_order

A variety of things can cause this kind of thing, some of the possivle  
causes are listed here  
[http://dev.mysql.com/doc/refman/5.0/en/gone-away.html](http://dev.mysql.com/doc/refman/5.0/en/gone-away.html)  
One that is particularly relevant in development mode is that mysql  
might time out your database connections if you are inactive for too  
long (whereas in the real worl you are far less likely to get no  
activity for long periods of time).

Thanks for the link Fred,

The weirdest thing is that I get the same error with Sqlite3, and it  
doesn’t use a client-server mode. In fact, I started getting that  
error in Sqlite3, that’s why I moved to Mysql just to face the same  
problem.

Any help you can lend me would be great guys.

Here is the error dump when it crashed on Sqlite3 (btw I’m using a  
windowsBox, and edgeRails):
