Symfony 3 Doctrine PHP Fatal error: Allowed memory size of X bytes exhausted (tried to allocate Y bytes)

Question

While trying to generate a database with a command:

php bin/console doctrine:schema:update --force

I'm getting these errors:

PHP Fatal error: Allowed memory size of 1073741824 bytes exhausted (tried to allocate 262144 bytes) in ...\vendor\doctrine\orm\lib\Doctrine\ORM\EntityManager.php on line 281

Fatal error: Allowed memory size of 1073741824 bytes exhausted (tried to allocate 262144 bytes) in ...\vendor\doctrine\orm\lib\Doctrine\ORM\EntityManager.php on line 281

PHP Fatal error: Allowed memory size of 1073741824 bytes exhausted (tried to allocate 262144 bytes) in Unknown on line 0

Fatal error: Allowed memory size of 1073741824 bytes exhausted (tried to allocate 262144 bytes) in Unknown on line 0

I have already tried all possible settings of memory_limit in php.ini, nothing helped.

With:

php bin/console doctrine:schema:update --dump-sql

the errors are:

PHP Fatal error: Allowed memory size of 1073741824 bytes exhausted (tried to allocate 262144 bytes) in ...\vendor\doctrine\orm\lib\Doctrine\ORM\EntityManager.php on line 281

Can we see the code you are working with? It looks like your PHP app is already using 1G of RAM, which sounds very excessive. — halfer

Which part of code do you need to see? It is a complete symfony application. As far I know, the schema:update command access only the mapping files in src\AppBundle\Entity. There are 18 of them in my application. 1024M is my current setting in php.ini. When I set it to 128M the error is PHP Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 262144 bytes) in ...\vendor\doctrine\orm\lib\Doctrine\ORM\EntityManager.php on line 281 — Chris Sz.

And tell us what's in your /etc/php or /etc/php5 directory. Probably you have different settings for web server and CLI. — Mateusz Sip

What happens if you use --dump-sql? Running out of memory on a schema update is strange. Maybe a mapping error. And run php --ini just to double check which ini file is being used from the console. — Cerad

I'm running the application locally. I've set php as environmental variable and run the application in command line. There is no such a directory like etc. Do you mean you need to see the php.ini file? — Chris Sz.

In my case, this error was caused by a very specific mistake:

My User mapping had a custom repository class set up. Said repository had a constructor like the following, which caused an infinite loop:

public function __construct(private EntityManagerInterface $manager)
{
    $this->repository = $manager->getRepository(User::class);
}

Since I didn't really need the custom repository, it was just a matter of removing it from the mapping.
