I use symfony 1.4 (from a task) and Doctrine 1.2 to import data from a lot of files.

It works well, but after a few minutes I get an “Allowed memory size exhausted” fatal error from PHP, not in my code but in Doctrine…

i’ve tried adding some “->free()” to Doctrine calls, but now it seems to fail on InverterTable->findOneBySerialNumber(), a “magic” Doctrine method.

How can I fix my problem ? Do I need to write my own “findOneBySerialNumber” method, adding a call to “free()” ?

    It’s such a common problem with doctrine. You have to use pcntl_fork.

    I always use this gist as an example.

    pcntl_fork doesn’t work on Windows because it requires an OS that follows the POSIX standards.

    It might also be enought to just help doctrine free objects its objects, here’s a great answer about that.

    If you got some The MySQL server has gone away:

    When using Doctrine and MySQL, it might be necessary to add the following of the child thread code:

    Doctrine_Manager::connection()->close();

    This will close the database connection, and Doctrine will automatically recreate it at the first query.
