Re: mysql errors in production after upgrading to rails 2

Correct, I perhaps did not give enough details.
From the console in production mode on that machine it works fine.
It is from the mongrel that it doesn't. It is essentially every query
from the mongrel, as far as I can tell. Just trying something now, it
is actually failing on occasion, in mongrel, even in development.

I've never seen these errors before:
!\ FAILSAFE /!\  Fri May 16 08:22:19 +0200 2008  Status: 500 Internal
Server Error
  You have a nil object when you didn't expect it!
The error occurred while evaluating nil.all_hashes    /usr/local/lib/
ruby/gems/1.8/gems/activerecord-2.0.2/lib/active_record/
connection_adapters/mysql_adapter.rb:482:in `select'

And the same query that I get this on:
ActiveRecord::StatementInvalid (Mysql::Error: Lost connection to MySQL
server during query:

I can run from the console.

So it definitely seem to be how mongrel is connecting to mysql. I am
not using the mysql gem (I wasn't before under 1.2.6 either) I am
connecting with the builtin mysql adaptor.
