Description:
Simply migrating from SQL Server 2008 to MySql.  All steps seem to be OK, no errors or issues or warnings about compatibility.  Everything is created, but then, during data transfer, it takes a very long time and finally crashes with error, Program can't continue, insufficient memory, or something like that.

How to repeat:
I was migrating 5GB database, schema, functions/view/stored procedured, and data.

Thank you for the bug report. Please check if related or duplicate of http://bugs.mysql.com/bug.php?id=66516 . Thanks.

This does look like it could be related to Bug #66516 but it is a bit hard to follow that since the errors are in Spanish/Portugese?  I can't see specifically if they are getting the out of memory error.  

I can duplicate this, I've run it twice.  Is there something I can provide to help prove this?

Thank you for the feedback. Please describe the steps you did and which point the crash happens. Thanks.

Hmmm, thought I did describe the steps in the original description.  I set up a migration using the wizard, SQL Server 2008 to MySql, migrating schemata, views, stored procedures, fuctions, and data.  Used all of the default settings.  Every stepped passed with no issues including the conversion report, no error or compatibility issues and all tables seemed to be created correctly.  The actual data migration started and was taking a very long time.  It eventually failed giving an out of memory error as described in the original report.

Any progress on this?  I'd really like to begin testing on our migrated database from MS SQL but I can't migrate because of this.
