Has anyone noticed that core/modules/rest/src/Plugin/rest/resource/EntityResource.php will try to allocate a huge amount of memory (over 200MB) at the end of the post() for a large variety of (>1MB) jpeg images?
It creates a memory exception at
"$response - new ResourceResponse(NULL, 201);" to be exact. It does not throw the EntityStorageException.
Why might the post in EntityResource.php try to allocate so much memory when trying to post an image, which, by the way, DOES get saved into files/private? What may validate() be doing?
Looks like it was a beta problem. Gone in RC2.
