Dear Maintainer,
First of all, sorry for my poor English.
/etc/init.d/apache2 start is completed before apache2 is really
started.
And, /etc/init.d/apache2 restart is completed before apache2 is
really restarted.
For example, if /etc/init.d/apache2 start and /etc/init.d/apache2
status are run continuously, it will be displayed as Apache2 is NOT
running..
But, if /etc/init.d/apache2 status is run after several seconds, it
will be displayed as Apache2 is running (pid )..

This symptom has a bad influence on operation of HA cluster resource
manager (such as pacemaker).
The attached patch corrects /etc/init.d/apache2 so that it waits for
apache2 to be really started or restarted.
Please review the attached patch, and if satisfactory, consider
including it in the package.
P.S.
It seems that this symptom does not occur when the load of apache is
low to some extent.
In our system, when some modules (such as perl, php5 and python) were
enabled, the above-mentioned symptom occurred.
But, when some modules (such as perl, php5 and python) were disabled,
even if I ran /etc/init.d/apache2 start and /etc/init.d/apache2
status continuously, it came to be immediately displayed as Apache2
is running (pid )..
Thanks,
