Issue #2590 has been updated by Luis Lavena. Hello, Reporting a segmentation fault from a Rails application without providing details about database configuration and others will not help determine the root of the segmentation fault. There are lot of variables to consider inside a Rails application. Also, could be this the cause of another library used in background either defined by you on config.gem / initializer or something else. Also database adapters can be the root of this segmentation fault. I guess you're running MySQL, and can bet version 5.1 with mysql-ruby gem 2.8.1 If I'm correct on the above, please read this: http://blog.mmediasys.com/2009/08/21/mysqlruby-2-8-1-released/ See the "Importance of MySQL version used" -- Luis Lavena ---------------------------------------- http://redmine.ruby-lang.org/issues/show/2590 ---------------------------------------- http://redmine.ruby-lang.org
