BrokenPipeError during file uploads from client disconnect or size limits

File upload operations throw 'BrokenPipeError: [Errno 32] Broken pipe' errors. Client disconnected during upload or file size exceeds configured limits in Django or web server (nginx client_max_body_size).

Check FILE_UPLOAD_MAX_MEMORY_SIZE in Django settings and nginx client_max_body_size directive. Wrap file processing with try/except to handle client disconnects gracefully. Validate file sizes before processing. Increase limits if legitimate large files are expected.
