Comment(by pmialon):

 We recompiled the package with the debug info, here a panic with correct
 references.

 Unfortunately we didn't have the coredump. We succeed to produce one but
 it was incomplete. Perhaps we need to use less space on our storage to
 keep place for the core ? Now we are dedicating 80% of the space to
 varnish store file.


 We start varnishlog and we will update this ticket with the content of
 Vary: header as soon as varnish will crash.
