Bug#603275: apache2: When machine is booting, Apache2 does not bind to IPv6 address - needs restarting

["G.P." <gpall@postmortem.csd.auth.gr>]

Package: apache2.2-common
Version: 2.2.16-3
Severity: important


When the machine is booting, apache does not bind to the IPv6 address:
postmortem:~# netstat -pan | grep LISTEN|grep apache
tcp        0      0 0.0.0.0:80              0.0.0.0:*    LISTEN      1440/apache2    
postmortem:~#

But after a restarting:

postmortem:~# /etc/init.d/apache2 restart
Restarting web server: apache2 ... waiting .
postmortem:~#
postmortem:~# netstat -pan | grep LISTEN|grep apache
tcp6       0      0 :::80                   :::*                   
LISTEN      10576/apache2   
postmortem:~#

it listens...

This was playing for a long time, but some weeks ago it started behaving
like that. The host is regularly kept up-to-date to debian squeeze.

Relevant apache config:

NameVirtualHost *:80
Listen 80

(in /etc/apache2/ports.conf)
