Symfony3 cache (Warning: rename) after update

Question

I have problem, after insert or update in my screen i see message:

Warning: rename(C:\Users\Name\Desktop\BaseApp\var\cache\dev/doctrine/orm/Proxies__CG__AppBundleEntityCategory.php.57483ae07bdb29.50220410,C:\Users\Name\Desktop\BaseApp\var\cache\dev/doctrine/orm/Proxies__CG__AppBundleEntityCategory.php):

All time after update i see this message, after reload page all is right, i use my app on windows, dev mode, symfony3,

The problem is that the Doctrine's proxy class generation code doesn't handle concurrent requests very well. It works on Unix-like systems, but not on Windows, where you can't just rename over a file that is open.

See configuration of the doctrine bundle. You'll most like have auto_generate_proxy_classes set to "%kernel.debug%" (this is the default setting in symfony standard edition).

Try changing auto_generate_proxy_classes to false. You'll now have to manually clear the cache if you change your entities, but that error should be gone.
