 Reporter:  geoff  |       Type:  defect
   Status:  new    |   Priority:  normal
Milestone:         |  Component:  varnishd
  Version:  3.0.3  |   Severity:  major
 Keywords:  gzip   |
-------------------+----------------------
 Varnish in production crashed with the assert error shown above, will
 attach the panic log.

 }}}

 This is Varnish 3.0.3 with various custom enhancements, but none of these
 affect gzip.
 This happens after an error status is returned from deflateInit2() from
 zlib; it might be better to throw a 503 when this happens, to avoid the
 crash.
