清除缓存时Symfony 4内存泄漏

Question

I have Symfony app which is built on Symfony 3, but recently I upgraded to Symfony 4. Now I have a problem when clearing cache. When I run command to clear cache I'm getting this error:

PHP Fatal error: Allowed memory size of 536870912 bytes exhausted (tried to allocate 32768 bytes) in var/cache/dev/ContainerGGUArAR/getDoctrine_Orm_DefaultEntityManagerService.php on line 85.

php.ini memory_limit is set to -1.

I found that ServiceEntityRepository is causing the problem, because when I extend this service to one repository I get this error.

Does somebody know what should I try to fix it?

Just to mention that memory_limit is set also for CLI to be unlimited

Answer 1

It is not the solution to the core of your problem but probably allows you to clear the cache even with very large contents:

Try

php -d memory_limit=-1 bin/console cache:clear

or when console is in app/ folder

php -d memory_limit=-1 app/console cache:clear

Or

rm -rf var/cache

or when cache is in app/ folder

rm -rf app/cache

I use "rm" very often instead of the bin/console command. This does not do any cache warmup so the loading of the first page will take longer. Sometimes I get better results clearing cache manually in comparison of the bin/console command...
