Hi Xing,

You get the honour of being the first "outsider" to report an

This particular assert indicates protocol trouble with a document
that uses "chunked encoding", usually a CGI script, and the most
likely trouble is that Varnish got out of step with the server somehow.

In theory the transaction should be the last in the varnislog so
if you run:
	varnishlog -d -w /tmp/foo
	(wait approx 10 seconds, then hit ctrl-C)
	varnishlog -r /tmp/foo | tail -200

You should get the information about which URL etc.

The easiest way to debug it from there would be if I could access
the server from here to pick up that URL, then I can see what
happens close up with a debugger, but if that is not possible
we will find another way.

Never attribute to malice what can adequately be explained by incompetence.
