Using 3.2.2, doing:
a = Model.where("created_at > '2011-10-01 00:00:00'").where("created_at < '2012-01-01 00:00:00'")
Always results in
ActiveRecord::StatementInvalid (Mysql2::Error: Lost connection to MySQL server during query: SELECT `models`.* FROM `models` WHERE (created_at > '2011-10-01 00:00:00') AND (created_at < '2012-01-01 00:00:00'))
If I leave off one of the conditions it works fine. The raw query via Mysql2::Client#query works fine, and returns within milliseconds, so it's not a timeout issue.
Any ideas? I'm stumped.
