I’m running rails 1.2.2 and mysql 5 on my linux server.

I recently had to install the rails 1.1.6 gem to run an app that  
requires it, and now I’m getting “Mysql::Error: Lost connection to  
MySQL server during query” on most urls in the app. The app was  
hitting the database with no problem s when I ran it using rails  
1.2.2, and i’m using an identical database.yml, so I know the login  
credentials are valid.

Any suggestions?

You’d been better off just putting Rails 1.1.6 in the vendor folder  
instead of installing the two gems.

Best regards

I’ve got 1.1.6 running in the vendor folder now, and I’m still getting  
the lost connection error.
