Jira issue originally created by user deatheriam:
\Doctrine\ORM\Proxy\ProxyFactory::generateProxyClass fails to rename temporary proxy files when proxies are generated on demand in multiprocess environment using Process Control extension under Linux (http://www.php.net/manual/en/book.pcntl.php). 'Message: rename(../cache/Proxy/Dlayer/__CG__DlayerEntityInventory.php.520d1708631ed2.21378588,/../cache/Proxy/Dlayer/__CG_\DlayerEntityInventory.php): No such file or directory' message is given.

The "dev" settings are not meant to be used for high concurrency environments at the moment.

Comment created by deatheriam:
Thats why you shouldn't generate proxies at runtime. The problem happens on windows, because the atomic rename operation doesn't work as perfectly there as on linux.
