Comment (by martin):


 Is this something that you are able to easily reproduce? We have failed to
 be able to reproduce this behavior...

 I have attached a patch to this ticket that adds some debugging log lines
 in order to better understand what is happening. Would you be able to
 apply this patch to your Varnish and rerun the tests?

 Our wishlist :)
 1) Apply the patch to the Varnish
 2) Set syncvsl debug flag (-p debug=+syncvsl)
 3) Capture varnishlog (varnishlog -g raw -O /tmp/varnish.log)
 4) Reproduce the bug
 5) Capture the panic report (varnishadm panic.show)
 6) Send log and panic message to the ticket.
