Varnish intermittently returns incomplete images

Our Varnish (test environment) intermittently returns incomplete images. So the binary content is not complete. When requesting the image from the backend directly (using curl), the complete image is returned every time (I tested 1000 times using a script).

This happens intermittently. Sometimes Varnish returns the complete image, sometimes half of it, sometimes 20% etc... The incomplete image is returned quickly, so I don't think there is a timeout involved (we have not configured any specific timeout in varnish).

I see nothing special in varnishlog when this happens. But I don't know how to troubleshoot this in a good way. Any suggestions?
