Does anyone get the following error at random?

Mysql::Error: Lost connection to MySQL server during query:

It only happens on my development machine which, unfortunately, is a  
windows  
box. It happens like every 10 clicks, but varies. I’ve got MySQL 5.

Yep, getting these since upgrading to 1.2 RC1 but I’m also getting the  
errors on edge. I am still investigating as to what is causing this to  
happen.

We’re experiencing the same thing with 1.2 RC1 also, but only on  
Windows machines. Hope someone figures it out before the release!

I thought the problem was still occurring even after [5637], but it  
turns out we had vendor/rails frozen to the 1.2 tag instead of the 1.2  
branch, so we didn’t have the fix. It seems to be working fine now.

Thanks for your help!

It happens to us all the time on 1.1.6 so we use a different Rails  
adapter  
for MySQL

Follow the directions here and see if that helps. I understand they  
tickered  
with the ruby-only mysql adapter in 1.2 so this might still be a better  
option:
