Description
Reported by a user, see RT 226297
User had created 10 datasets and uploaded 215 files, mostly PDFs and images, ranging in size from 10MB to 280MB.
They experienced their UI freezing and we received a server critical warning but it recovered.
We recommended for now that they upload fewer files at one time as a temporary workaround.

Research direction
Start by reproducing the reported upload scenario with many large PDF and image files, then trace the PrimeFaces image-processing path involved in file uploads. Done means the browser remains responsive and no server critical warning occurs when handling comparable batches; the issue names no specific files or tests.
