No, we have not tested streaming+gzip with varnish 4 yet. What I know is, that gzip errors occurred with both gzip and the experimental streaming enabled in varnish 3. Disabling streaming also made the gzip errors disappear, so we currently run varnish 3 with gzip enabled and streaming disabled.

Unfortunately, we are also not running varnish 4 in production yet, one reason is the missing stale-if-error feature (discussed in other threads), since our old hacky vcl "restart" code from varnish 3 some inline-c which emulated Stale-If-Error, didn't work any more in varnish 4, since backend and frontend are separate now and internal code has changed a lot, so our inline-c did not fit in.

We will retry streaming and gzip with varnish 4 as soon as s-i-e is properly implemented in varnish 4.x, so we are able to throw out the old vcl hacks and make our varnish 3 vcl files to work with varnish 4.

Kind regards
Daniel
