Symfony 3.4 - The EntityManager is closed - php

Question

I have an application run with Symfony 3.4 with MySql and I get a error: 'The EntityManager is closed'. My application running two ways:
1 - A Console application thats is called by a sh script every time. This console app make many inserts in a database table.
2 - A HTTP Route that also insert in same table.
When de console app is running in background if i call the http route i get the error 'The EntityManager is closed'. If I stop de backgroud app the http route works. It's as if the two apps console and http use the same instance EntityManager.
My code:
I Create a service called AbstractRepositoryService. All of my services that manage repositories should extend.
<?php
abstract class AbstractRepositoryService
{
/**
*
* #var EntityManagerIntergace - $em
*/
protected $em;
/**
*
* #param EntityManagerInterface $em
*/
public function __construct(EntityManagerInterface $em) {
$this->em = $em;
}
/**
*
*
* #param String
*
* #return #mixed
*
* #throws RuntimeException
*/
public function __call($method, $args) {
$repository = $this->em->getRepository(static::ENTITY);
if (!method_exists($repository, $method)) {
throw new RuntimeException(
sprintf("Method '%s' not found.", $method),
500
);
}
try {
return call_user_func_array(array($repository, $method), $args);
} catch(Exception $e) {
throw new Exception($e->getMessage(), 500);
}
}
}
My UserRepositoryService where the exception is thrown in the flush method
<?php
final class UserRepositoryService extends AbstractRepositoryService
{
/**
*
* #const String
*/
const ENTITY = 'AppBundle\\Entity\\User';
/**
*
* #param User
*/
public function insert(User $user) {
try {
$this->em->persist($user);
$this->em->flush($user);
} catch (Exception $e) {
throw new Exception($e->getMessage(), 500);
}
}
}
And finaly my service declaration:
app.services.user_repository_service:
public: true
class: AppBundle\Services\UserRepositoryService
arguments:
- '#doctrine.orm.entity_manager'

Solved!
I created a method that generate new EntityManager before insert and works now.
protected function createNewEntityManager() {
return $this->em->create(
$this->em->getConnection(),
$this->em->getConfiguration(),
$this->em->getEventManager()
);
}
And in insert:
public function insert(Crawler $crawler) {
try {
$this->createNewEntityManager();
$this->em->persist($crawler);
$this->em->flush($crawler);
$this->em->close();
} catch (Exception $e) {
throw new Exception($e->getMessage(), 500);
}
}
