Problem when creating password token in eventSubscriber

[D3xime]

Hello everyone, i encounter some problems. I want to genrate a token when an user change status. To achieve that i used an eventSubscriber like below. But when i try to do it i got a fatal Error because i used too much RAM. Any idea how I can achieve that ? I am pretty new with this bundle and any help will be pleased. If i miss something feel free to say it to me
