Description Vadim Kuznetsov (RETIRED) gentoo-dev 2012-04-16 17:55:14 UTC
It seems to me that start case of apache init script should include --pidfile option like so:
start-stop-daemon --start --pidfile "${PIDFILE}" ${APACHE2} -- ${APACHE2_OPTS} -k start

s-s-d will try to find out if service is already runnig and will try to stop it before it will attempt to start it.
If you don't supply --pidfile,  s-s-d will look for service in /proc by name.

It's all fine, unless you have lxc container that is running apache as well.
s-s-d will find container apache in /proc by name, then it will try to kill it (this is already not what we want.) and fail. 
And after that s-s-d will fail to start service on the host on the ground that is already running.
If you supply --pidfile s-s-d will search /proc by pid only and will not find service running in the lxc container.

The pidfile issue also affects running multiple apache instances:

has no affect.

The pidfile is still created as
even though the rest of the conf variables are used,
such as STARTUPERRORLOG="/var/log/apache2/pmirror-startuperror.log"

A possibly related issue is that the startup is delayed for 5 seconds
or so.
