Startup services in linux are running twice

Question

When I reboot my Ubuntu 10.04 32 bit machine all the startup services are started twice.

The startup process looks like this:

Starting apache2
Starting apache2 
(98)Address already in use: make_sock: could not bind to address 0.0.0.0:80 
no listening sockets available, shutting down 
Unable to open logs 
 Done 

 Done 

 * Starting MySQL database server mysqld        * Starting MySQL database[ OK ]  * Starting nsd3...        * Starting nsd3...
                                                                             [ OK ] 
 * Starting Postfix Mail Transport Agent postfix        * Starting Postfi[ OK ] Transport Agent postfix        
                                                                             [ OK ] 
 * Starting NTP server ntpd        * Starting NTP server ntpd            [ OK ] 
Starting daemon monitor: monit. 

I checked I don't have duplicate startup links, if I do an update-rc.d -f mysql remove then reboot mysql doesn't start at all, re-adding it still makes is start twice.

The only things in my logs are warnings about everything starting twice.

Has anyone seen this before or have a clue where to poke to find out whats causing it?

Solution 1

Found the problem, I had a duplicate copy of /etc/init/rc.conf so upstart was running /etc/init.d/rc twice.

Solution 2

I'd guess that your system is possibly going through two runlevels and executing the start scripts in each.

First I'd look at /etc/rc2.d, /etc/rc3.d, /etc/rc4.d - and remove all but one of the start symlinks and see if that works.

Use the "runlevel" command to see what runlevel you are currently in.
