I managed to "fix" this, but I could use some perspective.
The first article is successfully added to lr_article,
lr_article_translation and dm_page_translation.
All subsequent articles are only added to lr_article and
lr_article_translation, but not dm_page_translation.
In diem-5.1.3/symfony/lib/plugins/sfDoctrinePlugin/lib/vendor/doctrine/
Doctrine/Connection.php on line 911, I added:
$this->setAttribute(PDO::MYSQL_ATTR_USE_BUFFERED_QUERY, true);
This doesn't seem like a good solution to me, but it fixes it.
If there is a way to set this in databases.yml, it would make more
sense, but I get an error when attempting this.
According to
http://www.symfony-project.org/reference/1_4/en/07-Databases,
MYSQL_ATTR_USE_BUFFERED_QUERY is not an attribute that can be set.
What I don't understand is, I've read in multiple places that
MYSQL_ATTR_USE_BUFFERED_QUERY is set to true by default as of 5.2.1,
but I'm using 5.3.2 and still had to set this manually.
