Comment (by anders):

 It seems that Varnish again has this bug. I removed IPv6 support from my
 kernel, I use -T localhost:8080 and have this in /etc/hosts:

 {{{
 ::1                    localhost localhost.my.domain
 127.0.0.1               localhost localhost.my.domain
 }}}

 If I try to start Varnish, it crashes:

 {{{
 Starting varnishd.
 Classic hash: 500009 buckets
 Using old SHMFILE
 socket(): Protocol not supported
 Assert error in mgt_cli_telnet(), mgt_cli.c line 478:
   Condition(sock >= 0) not true.
   errno = 43 (Protocol not supported)
 Abort trap (core dumped)
 }}}

 . Backtrace:
